One piece white polypropylene sheet for DIY, engineering and machining projects. Size 400 mm x 300 mm x 10 mm (the listing also shows 300 x 400 x 10 mm). This sheet is designed to provide a lightweight, durable work surface and fabrication material for a wide range of workshop tasks. Key benefits Lightweight yet sturdy: provides a stable work surface and solid foundation without the weight of metal plates. Moisture and chemical resistance: suitable for use in typical workshop environments where moisture exposure or light chemical contact may occur. Easy to machine: can be cut, drilled, and milled with standard workshop tools, then finished by deburring to create clean edges. Reusable and cost effective: durable enough for multiple projects and templates, reducing the need for replacement boards. Visually clear and consistent: white surface aids marking, layout, and alignment for precise work and documentation. Key attributes Material: Polypropylene (PP) Color: White Size: 400 mm x 300 mm x 10 mm (listed as 300 x 400 x 10 mm in the product listing) Quantity: 1 piece Applications: suitable for DIY, engineering, and machining projects Functionality: serves as a work surface, template, spacer, prototype plate, or backing/fixturing material Compatibility: compatible with common fasteners, adhesives and standard tool cutting methods used in hobbyist and professional environments Performance: provides a stable, inert surface that resists moisture and typical workshop exposure Use cases and applications DIY jigs and fixtures: cut to size, used as a drilling or routing template, or as a backing plate for mounting parts during assembly. Engineering prototyping: create lightweight prototypes, spacer blocks, or temporary mounting plates for testing ideas and layouts. Machining support surface: use as a sacrificial, reusable work surface or as a backing board to protect workpieces during cutting, sanding, or drilling. What makes it suitable for your projects The sheet combines ease of handling with sufficient rigidity for layout, measurement, and fixture work. It provides a clean, neutral background for marking and aligning components, improving accuracy and repeatability. Its polypropylene composition offers durability in a range of workshop conditions while remaining easy to work with using common tools. Care and handling Cut and shape with standard tools appropriate for polypropylene. Deburr edges after machining for a smooth finish. Store in a dry environment to maintain surface quality and dimensional stability.
