Our retractable aggregate bay covers provide an innovative waterproof covering solution to protect all types of bulk products being stored outside.

At Stuart Canvas, we specialise in crafting retractable bay covers that can function independently, catering to both single and multiple bays. Our covers feature a wall-mounted tracking system, enabling seamless retraction & traction for the hassle-free loading and unloading of products. Choose between a manual or electric retracing system for each bay, providing swift and efficient closure within minutes. The framework of our retractable covers boasts a box section of galvanized steel, ensuring a robust and durable system.

Our comprehensive systems include protective measures for the front and rear of the bays, effectively preventing water ingress from all sides. This innovative solution has demonstrated remarkable results, particularly in safeguarding kiln-dried products, leading to a noteworthy reduction in wastage of up to 30%.

PVC material is durable, sturdy, waterproof, and tear-resistant, giving it versatile applications. PVC is simple to maintain; it can be cleaned with a wet towel or washed with soapy water. It is waterproof with great weather resistance, including rain, snow, hail, UV rays, and frigid temperatures. We offer PVC in 580gsm to 900gsm weights with our most popular being 610gsm, which offers a great balance between performance and aesthetics. PVC is also available as a fire retardant option.

Stipped PVC

Manufactured from 580gsm PVC, this durable PVC comes in a variety of striped colours, making them versatile for different aesthetics. Specifically for canopies and market stalls, they offer ideal protection against the elements, being both waterproof and UV stabilised, ensuring longevity and reliability in outdoor settings.

Clear PVC  is ideal for creating window sections in tarpaulins and covers, to allow extra light through. Clear PVC is available in 580gsm and 610gsm weights. It is UV-stabilised and offers the same waterproof and weather protection as coloured PVC.

Polyester Cotton Canvas

Our heavy duty polyester cotton canvas fabric is a woven fabric with a composition of 50% Polyester and 50% Cotton. It is naturally breathable, and its ability to regulate temperature and moisture makes canvas fabric unique. This water-resistant material creates an organic look and feel.

Recyclable Polypropylene

This recyclable material offers a fabric weight of 350gsm whilst providing a tensile strength that is greater than a heavy duty PVC of 610gsm. The material is entirely PVC-free as it is manufactured from recyclable polypropylene. It can come with a polypropylene rope inside the hem. It also has a high UV durability of at least 5 years for Northern Europe. Recyclable polypropylene can be used on any application in which PVC would typically be used. It is also available in an extra-heavy duty 600gsm weight.

Ripstop Canvas

Durable and stylish multi-purpose ripstop fabric is available in a range of vibrant colours. Ripstop Canvas is a specially woven fabric that prevents tearing and ripping, making it ideal for projects that require the organic look of canvas but need the strength and durability that ripstop can provide.

Woven Polyester

Woven Polyester offers the perfect balance of science, toughness and style. It is a lightweight, highly water resistant, breathable, non sagging and durable fabric, ideal for covers, awnings, UV strips, upholstery, cushions, umbrellas and sun shades. It is available in two weights with various finishes and a wide range of colours to suit all applications.

Windbreak Mesh

Specially designed windbreak material is manufactured from robust polypropylene. It is UV stabilised, making it ideal for year round outdoor use. The material blocks the majority of wind from passing through, creating a still air area behind it. The porous nature of the martial prevents it from acting like a sail in high winds, while still offering protection.

Geo Textile

Designed to provide a controlled environment for the germination of grass. It also provides frost damage protection to grass during freezing conditions. It is manufactured from 155gsm black porous material which can be produced as a single skin to a triple skin cover.

PVC Mesh

Heavy duty PVC mesh is an extremely strong hard wearing fabric with a high tensile strength. The mesh allows for wind to pass through while still creating a strong barrier; it is ideal for areas requiring increased ventilation. It can also be added to PVC material to create an opening, for example, to create a window on a PVC machine cover to the retractable tunnel.

Semi - Translucent

Our semi-translucent material is reinforced and designed to allow sunlight through onto the grass below in sporting venues. It is available in set and bespoke sizes, and we can add reinforced hems, eyelets, and grab handles.

Netting

We can offer a wide range of netting weights and materials. These can be used in ball sports as ball stop netting and in mobile batting cages. Our netting can also be used in industry as debris netting and cargo nets. Our netting is available in a range of colours to suit all uses.
