UV Resistance
All Hengyue pultruded gratings are manufactured with resins containing UV inhibitors. UV resistance is enhanced with the use of a synthetic surfacing veil, creating a " resin rich" surface, and further strengthening Hengyue pultruded grating resistance to UV attack. Impact Resistance

Hengyue Pultruded Gratings offer better impact resistance than conventional steel gratings.

Fire Retardancy

All Hengyue pultruded gratings are designed to exhibit a flame spread rating of 25 or less test in accordance with ASTM E-84 tunnel test, and meet the self-extinguishing requirements of ASTM D-635. A variety of resins are available offering an array of flame spread ratings and smoke densities.

Non-Skid And Safety

All Hengyue pultruded grating are equipped with a durable and permanent gritted surface on the topside of all bearing bars, thus providing superior slip resistance as compare to traditional steel grated walking surfaces.

Thermally And Electrically Non-Conductivity Hengyue pultruded grating is both thermally and electrically non-conductive, two features that make it a desirable product in many applications such as those involving electrical and fire hazards. The thermal non-conductivity feature of Hengyue pultruded grating protects individuals from the head radiation that occurs on traditional steel grating during fires-firefighters can get and stay closer to the fire source for linger periods of time.

Low Maintenance/Maintenance Free

With resin and pigment blended throughout Hengyue pultruded grating, you never need to coat or paint the product---it simply does not rust. Coupled with our 316 stainless steel attachment systems, Hengyue pultruded grating offers" maintenance-free" walkway systems. You install it and forget about it !
