Construction
GRP Gratings are produced by wet molding and hot curing in a heated mould. The reinforcement consists of continuous fiberglass rovings in alternating layers. So the loads are distributed evenly in all directions.
Design
Regularly Molded GRP Gratings have a polyester resin matrix. Glass content is approximately 35%. Standard colors are green, yellow or grey, other colors are available according to RAL.
Excellent Properties
1. Corrosion and chemical resistant
Corrosion is a major problem for metal or wooden grating, stair treads and other products in many different industries such as chemical plants, food and beverage factories, water and wastewater facilities, power facilities. LOREN ®grating is particularly designed to provide safe, long-lasting, economical and worry-free solutions in environments where chemicals and other corrosive materials attack and destroy metal or wood. According to different environmental requirements, such resins as orthophthalic polyester, is ophthalmic polyester, vinylester or phenolic are chosen as matrix material.
2. High strength-to-weight ratio
LOREN ®grating manufactured as a composite of continuous fiberglass strands and high quality resin is integrally constructed for strength, but it is less than one-half the weight of steel grating allowing easy removal for access below floor level and installation with no heavy equipment and less manpower. Properly installed, LOREN ? gratings meet specified load requirements for steel and are more impact resistant than metal.
3. Fire retardant
LOREN ®grating has flame spread rating of 25 or less depending on different resin systems as tested in term of ASTM E-84. Test Report can be offered upon request. Special fire retardant requirements can also be met by adding extra additives.
4. Ergonomic
Employees are experiencing fatigue after standing on solid concrete or heavy non-adjustable galvanized steel platforms all day, LOREN ®gratings are the best solutions to ease the strain on the backs, feet and legs of workers increasing workers’ comfort and productivity due to its natural slight resiliency that makes them comfortable to stand on for a long period.
5. Slip-resistant
LOREN ®molded grating has a concave top surface for slip resistance after it is extracted from the mold. Should a grit surface be specified, the grit would be either bonded to the top of the completed grating as a secondary operation or embedded to the top of grating before heating, both providing superior slip resistance. Diamond cover top or gritted cover top are also available upon request.
6. Anti-aging
More than 20 years of Life is guaranteed for LOREN ®FRP gratings.
7. Easy maintenance
Install it and forget about it. LOREN ®grating is easy to clean, its open meshes permitting debris to fall through grating panel and preventing hazardous buildup on walking surface. .
