Manufactured by Sui Generis in GB
Sui Generis International Ltd was established in 1996 and in 2016 celebrated our 20th anniversary year in business. From the gradual progression of bespoke GRP (Glass Reinforced Plastic) moulded products, the company has grown to specialise in a wide variety of fibreglass applications, including the introduction of the GRP Grating and Safe Tread Anti-Slip Stair and Floor products.
Safe Tread anti-slip stair & floor products
As part of our gradual expansion we have invested in and recently expanded our anti-slip manufacturing facility which now sees us produce premium quality stair and floor products at extremely competitive rates here in the UK.
Top quality premium products

As the manufacturer, we are able to achieve the highest standards of quality control as well as refining and introducing new products, custom sizes, and custom colours for our customers. We take great pride in being one of the only UK manufaturers within our industry and actively reduce our (and your!) carbon footprint by avoiding imports from overseas.
Delivery throughout the UK
We provide to both business and home users and our speedy service despatches across the UK. Longer lead times apply to custom or larger orders.
Sustainability
![]()
We’re proud to manufacture our non-slip GRP product range using a specialist, super-strength, resin made from recycled plastic bottles, diverting them from landfills and our oceans. Over 1,800 recycled plastic bottles are saved in every 220kg drum of resin we use. We are continually researching ways to reduce our carbon footprint and are hoping to expand this into other ranges as soon as possible.
Customer satisfaction
As a company, we pride ourselves in the knowledge that we have never let our growth distract us from our core value of offering excellent customer service no matter the size or nature of the job.
We are committed to providing the best quality products and service in all areas, from receiving your order by phone or online to manufacturing the product, right through to packing and delivery to you.

Having first achieved ISO 9001 accreditation in 2002 our Quality Management System and associated procedures are now firmly ingrained into our everyday practices, this combined with the fact that many of our site operatives have been with us for over a decade means that stringent quality control has become second nature. |
