Plastic V-Blocks for Pipes, Shafts, Round Bars & Coils

Plastic V-Blocks for Pipes, Rolls, Shafts, Round Bars and Coils

Plastic V-blocks and storage prisms are used wherever round, cylindrical or roll-shaped goods must be stored, positioned, transported or secured in a controlled way. Pipes, shafts, round bars, coils, rolls and other cylindrical components are difficult to handle because they naturally tend to roll, slip, twist or move during storage and transport. A flat surface is rarely enough. Without a defined support system, round material can shift inside a warehouse, move on a pallet, damage surrounding parts or create unnecessary risks during internal handling and truck transport.

Our custom plastic V-blocks and storage prisms are designed to solve exactly this problem. They provide a stable V-shaped support surface that keeps cylindrical parts in a defined position. Depending on the application, the V-grooves are CNC-machined from solid plastic material or produced as 3D-printed custom supports from technical filament. This allows Plastic Union to supply both robust heavy-duty solutions for large diameters and flexible small-batch solutions for prototypes, special dimensions and individual geometries.

The result is a practical, reusable and durable support system for industrial storage, production logistics and load securing. Plastic V-blocks can help prevent rolling, slipping and surface damage. They improve order in storage areas, reduce search times, protect sensitive components and support safer handling processes. Whether you need a single custom V-block according to drawing or a series of storage prisms for recurring transport processes, Plastic Union supplies tailored solutions for pipes, shafts, round bars, rolls, coils and cylindrical material.

Why Round Material Needs a Defined Support System

Round material is one of the most difficult product groups to store and transport safely. Pipes, rods, shafts and rolls have no stable flat base. If they are placed directly on a pallet, on a shelf or on the floor, they can move as soon as the surface is not perfectly level or when the pallet is handled by a forklift. During transport, braking, cornering, vibration and loading movements can increase the risk of movement even further.

In many warehouses and production areas, improvised solutions are still used: wooden blocks, cut timber, cardboard spacers, foam scraps, simple wedges or metal supports. These solutions may work temporarily, but they often lack precision, durability and repeatability. Wood can splinter, absorb moisture and vary in shape. Metal supports can scratch sensitive surfaces. Soft materials may deform under load. A custom plastic V-block provides a more controlled and repeatable support surface.

A V-shaped support creates a defined contact area for cylindrical parts. The component is guided into the groove and remains in a predictable position. The support does not need to grip the part aggressively; the geometry itself helps create stability. This makes plastic V-blocks useful for storage, production supply, packaging, internal transport and load securing applications.

Version 1: CNC-Machined Plastic V-Blocks from Solid Material

The first manufacturing option is the CNC-machined plastic V-block made from solid material. This version is particularly suitable for heavy loads, larger diameters, long-term use and recurring industrial applications. The V-grooves are machined precisely according to your drawing, diameter, support angle or application requirements. This allows the support to match the geometry of the part as closely as possible.

The base material consists of solid StruCo plastic sheets and beams made from a PE/PP-RE mix. This recycled polyethylene/polypropylene regranulate blend is robust, weather-resistant and suitable for many industrial environments. It is impact-resistant, moisture-resistant and resistant to many common chemicals. Compared with many temporary wood-based supports, it offers a long service life and consistent dimensional stability.

Technical Data for the CNC-Machined Version

• Material: PE/PP-RE mix, robust recycled plastic material
• Manufacturing: CNC-machined from solid sheets or beams
• Length: up to approx. 1150 mm, depending on design
• Thickness: typically approx. 50 mm or 100 mm
• V-grooves: manufactured according to drawing or specification
• Geometry: single V-groove, multiple V-grooves, radius support or custom contour
• Options: blind holes, mounting holes, rubber inserts or anti-slip elements on request
• Application: pipe storage, shaft support, round bar storage, coil support and load securing

CNC-machined plastic V-blocks are the right choice when dimensional accuracy, load capacity and durability are important. They can be designed for a specific pipe diameter, a particular shaft geometry or a defined storage system. The machined V-groove offers repeatable positioning and a stable support surface. This is especially useful when the same component is stored, transported or handled repeatedly.

Version 2: 3D-Printed Storage Prisms and Custom V-Blocks

For prototypes, special geometries and small quantities, Plastic Union also offers 3D-printed storage prisms and V-blocks made from technical filament. This manufacturing method is ideal when a conventional tool would be too expensive, when the required quantity is small or when the geometry needs to be tested before series production.

3D printing allows a high degree of flexibility. V-angles, radii, wave profiles, modular plug-in systems, recesses, lightweight structures and customer-specific features can be implemented without tooling costs. This makes 3D-printed V-blocks a practical solution for development departments, maintenance teams, machine builders and logistics planners who need a fast and economical support solution for special parts.

Available 3D-Printing Materials

• PETG – suitable for food-contact applications, chemical-resistant and dimensionally stable
• ABS – impact-resistant, temperature-resistant up to approx. +100°C and suitable for post-processing
• ASA – UV-resistant, weather-resistant and suitable for outdoor use
• PA / Nylon – extremely tough, abrasion-resistant and suitable for high mechanical loads
• PET-CF – carbon-filled, stiff, lightweight and suitable for demanding industrial applications

Benefits of 3D-Printed V-Blocks

• Economical for small quantities starting from one piece
• Short lead times without tooling costs
• Custom geometry according to CAD drawing, sketch or sample part
• Suitable for prototypes, test fixtures and pilot series
• Material selection based on load, temperature and operating environment
• Possible design features: V-angle, radius, multi-support, plug-in connection or mounting holes

3D-printed V-blocks are not intended to replace every heavy-duty CNC-machined support, but they are extremely useful where flexibility is the main requirement. They allow users to test a support geometry quickly, adapt it to a specific component and later decide whether a CNC-machined or series solution is required.

Plastic, Foam or Rubber – Selecting the Right Support Material

Plastic Union can supply V-blocks and storage prisms made from different materials depending on the application. Plastic is a good all-round choice for robust, reusable and dimensionally stable supports. Foam can be useful for very sensitive surfaces or lightweight components. Rubber can provide additional anti-slip performance where a higher coefficient of friction is required.

The right material depends on the component surface, component weight, storage environment, transport conditions and required service life. A polished shaft may require a more surface-friendly support than a rough steel pipe. A heavy coil may require a stronger support geometry than a lightweight plastic tube. A part stored outdoors may require UV-resistant material. A part transported on a truck may benefit from additional anti-slip elements or rubber inserts.

Typical Material Selection

• Plastic V-blocks: robust, reusable, weather-resistant and suitable for many industrial applications
• Foam supports: suitable for sensitive surfaces, lightweight components and protective packaging concepts
• Rubber storage prisms: useful where additional grip, friction or anti-slip performance is required
• 3D-printed technical plastics: ideal for prototypes, small batches and complex custom geometries

Applications for Plastic V-Blocks and Storage Prisms

Plastic V-blocks are used in many industrial areas. They are particularly useful where round goods need to be stored in a structured way, where surface protection matters or where transport safety must be improved. Because the supports are custom-made, they can be integrated into existing storage systems, pallet systems, pallet boxes, transport frames or production processes.

Typical Applications

• Pipe storage in warehouses and production areas
• Shaft storage in mechanical engineering and machining
• Round bar storage and bar stock handling
• Coil support and roll positioning in metal processing
• Support of cylindrical components on pallets
• Load securing during truck transport
• Internal transport between production, storage and shipping
• Protection of precision parts during handling
• Defined positioning inside pallet boxes or transport containers
• Storage aids for rail vehicles, automotive, plant engineering and maintenance

Pipe Storage – Preventing Rolling and Surface Damage

Pipe storage is one of the most common use cases for plastic V-blocks. Pipes are often stored in bundles, racks, boxes or on pallets. Without a defined support, they can roll into each other, damage their surfaces or shift during handling. This applies to steel pipes, stainless steel pipes, aluminium pipes, copper pipes and plastic pipes.

A V-block creates a defined resting point. It helps separate the pipe from the storage surface and reduces uncontrolled movement. When several supports are used in parallel, pipes can be stored in a more structured and space-saving way. This improves order in the warehouse and makes it easier to identify, pick and handle the right material.

Shaft Support – Protecting Precision Components

Shafts, axles, drive shafts and precision-machined round parts often have demanding surface requirements. Scratches, pressure marks or dents can lead to quality issues, rework or scrap. A plastic support surface is generally more component-friendly than a metal support, while still providing enough stability for industrial use.

Custom V-blocks can be designed to match the shaft diameter and the required support length. This helps avoid point loads, unstable positioning and unnecessary contact between components. For particularly sensitive shafts, foam or rubber inserts can be considered. This makes the support concept adaptable to the value and sensitivity of the stored parts.

Round Bar Storage and Bar Stock Handling

Round bars, rods and bar stock are common in metalworking, plastics processing and mechanical engineering. They are often stored in different diameters, lengths and materials. If storage positions are not clearly defined, picking becomes slower and the risk of mix-ups increases. A structured support system can help create visible order.

Plastic V-blocks can be used to separate bar stock by diameter, material or order. They can be placed in shelves, pallet boxes, transport containers or on pallets. Combined with labelling or colour coding, they support faster identification and cleaner material flow. This is particularly useful in production environments where small delays and repeated search times add up over time.

Coil and Roll Support

Coils and rolls require stable support because their weight and round geometry can create significant movement forces. Depending on the diameter and weight, a custom support geometry may be needed. Plastic storage prisms can be designed with wider support surfaces, multiple grooves or a geometry that matches the specific roll diameter.

For coil support, it is important to consider not only the diameter but also the weight distribution, surface sensitivity and transport method. A stable V-shaped support can help position the coil more securely. If additional friction is required, rubber inserts or anti-slip elements can be integrated into the support concept.

Load Securing and Transport Safety

Plastic V-blocks and storage prisms can support load securing concepts for cylindrical goods. They help create a more stable base, reduce rolling movement and support a form-fit approach where suitable. However, the final load securing concept must always be evaluated according to the specific load, vehicle, weight, friction values, lashing equipment and transport conditions.

For road transport in Germany and Europe, companies often refer to recognised cargo securing principles such as the VDI 2700 series and European load securing guidelines. More information on load securing can be found at the official VDI overview for VDI 2700 Load Securing on Road Vehicles, the BG Verkehr information on load distribution and securing and the EU guidelines on safe cargo securing for road transport.

These external references do not replace an application-specific load securing assessment. They are included as helpful technical background for companies that handle pipes, shafts, round bars, coils and other round material. In practice, plastic V-blocks are often used together with pallets, pallet collars, pallet boxes, wedges, anti-slip mats, layer pads and suitable lashing equipment.

Why Plastic Instead of Wood or Metal?

Plastic V-blocks offer several advantages compared with wood or metal. Wood is widely used because it is easy to process, but it can splinter, absorb moisture, vary in quality and wear quickly in repeated use. It may also create dust, fibres or inconsistent support surfaces. For modern reusable logistics, this is often not ideal.

Metal supports are strong, but they are not always component-friendly. They can scratch sensitive surfaces, corrode depending on the material and require additional protective layers. They can also be heavy, which increases handling effort. Plastic provides a useful balance between stability, durability and surface protection.

Advantages of Plastic V-Blocks

• Reusable and suitable for repeated handling cycles
• Splinter-free compared with wooden supports
• Moisture-resistant and weather-resistant depending on material
• Component-friendly compared with many metal supports
• Customisable by CNC machining or 3D printing
• Suitable for many industrial storage and transport processes
• Can be combined with rubber inserts, holes or additional fixing elements

Custom-Made According to Drawing, Sketch or Application Details

Every application is different. The right V-block for a small precision shaft is not the same as the right storage prism for a heavy pipe bundle or coil. That is why Plastic Union manufactures storage prisms according to your specifications. You provide the diameter, length, support surface, required quantity and application details. We support you in selecting the right manufacturing method and material.

A drawing is helpful, but not always required. A sketch, sample part, photo or description of the storage situation is often enough for the first assessment. Important information includes the diameter of the round material, the weight per part, the number of parts per support, the storage environment, the handling method and whether the support will be used only in storage or also during transport.

Information Required for a Custom V-Block Inquiry

• Type of component: pipe, shaft, round bar, roll, coil or cylindrical part
• Diameter or diameter range
• Approximate weight of the component
• Required support length and number of V-grooves
• Material preference: plastic, foam, rubber or technical filament
• Use case: storage, production, internal transport or truck transport
• Required quantity: single piece, small batch or series production
• Special requirements: holes, rubber inserts, anti-slip surface or colour coding

Integration into Pallets, Pallet Boxes and Pallet Collars

Plastic V-blocks can be integrated into existing load carrier systems. They can be placed directly on pallets, inserted into pallet boxes or combined with pallet collars. This makes them suitable for reusable logistics and internal material flow. When round material is placed into defined support points, packing density can improve and contact between parts can be reduced.

In pallet boxes, two or more rows of V-blocks can create organised storage channels for pipes, shafts or rods. On Euro pallets, custom supports can be used with pallet collars to create a reusable transport unit. For sensitive surfaces, additional foam or rubber protection can be added. For higher friction requirements, rubber inserts or anti-slip mats may be considered.

Industries and Use Cases

Mechanical Engineering

Mechanical engineering companies often handle shafts, axles, turned parts, precision tubes and machined round components. Plastic V-blocks help protect these parts during storage and internal transport. They can be adapted to specific diameters and support lengths, making them useful for both single parts and recurring series.

Metalworking and Steel Distribution

In metalworking and steel distribution, round bars, pipes and rods are stored in many dimensions and materials. V-blocks support structured storage, reduce uncontrolled movement and help create clearer material organisation. This can improve picking speed and reduce damage during handling.

Automotive and Supplier Industry

Automotive suppliers often transport shafts, tubes and cylindrical parts between production steps or to assembly locations. A reusable plastic support can be integrated into pallet-based systems and used repeatedly. This supports clean, structured and predictable logistics processes.

Maintenance, Repair and Workshop Use

Workshops, maintenance departments and repair operations need simple but reliable support solutions for shafts, tubes, rollers and cylindrical components. A custom plastic V-block can be used as a storage aid, assembly support or positioning aid during repair and inspection work.

Packaging and Shipping

For shipping, the support concept must prevent movement and protect the component. Plastic V-blocks can be combined with pallets, boxes, layer pads, straps or additional securing elements. This can help reduce transport damage and improve the repeatability of packaging processes.

Economical and Sustainable in Reusable Logistics

Reusable support systems can reduce the need for disposable packaging materials. Instead of cutting new wood blocks or using improvised one-way supports for every shipment, plastic V-blocks can be used repeatedly. This can reduce material consumption, waste and handling variation over time.

The economic benefit depends on the application, the number of cycles, the value of the protected parts and the cost of damage or rework. In many cases, a durable support system pays for itself by reducing transport damage, improving storage order and saving handling time. For high-value precision parts, even preventing a small number of scratches or damaged components can justify a custom solution.

Plastic V-Blocks, Storage Prisms, Pipe Supports or Shaft Supports?

Different industries use different terms for similar support solutions. In English, common terms include plastic V-blocks, V-supports, storage prisms, pipe supports, shaft supports, grooved supports, roll supports and anti-roll supports. The right term depends on the application and the market. For technical buyers, “plastic V-blocks” is often the most immediately understandable term because it describes the visible V-shaped geometry.

Plastic Union uses both terms: plastic V-blocks for the international search and buyer language, and storage prisms for the technical product family. This helps international customers understand the product quickly while still covering the broader industrial terminology used in warehouse logistics, load securing and component storage.
