Molded Grating, also known as FRP molded grating or GRP mesh grating, is a high-quality solution for various industrial applications. It is made from polyester resin and continuous fiberglass roving, which are heat cured in a mold using a meticulous layer-by-layer process. This results in a grating with the desired thickness and panel size.

With a glass fiber reinforcement of 30-35% (total weight), molded grating offers exceptional strength and durability. Its one-piece interwoven mesh construction provides optimal corrosion resistance and bi-directional strength. Unlike pultruded grating that relies on glued joints, molded grating is cast in one piece, eliminating the risk of joint failure under heavy continuous traffic or prolonged service.

One of the key advantages of molded fiberglass gratings is the high resin content of 65%, which ensures superior corrosion resistance and impact resistance. Additionally, its square mesh pattern enhances load capacity and panel utilization, making it ideal for demanding applications.

To cater to different requirements, molded grating offers a choice of surface finishes. You can opt for a smooth, concave, gritted, or solid-top surface based on your specific needs.

1.Excellent properties of frp grating as follows:

(1).Safety:FRP is recommended when corrosion protection and safety are your goal.
(2).Stability:Expansion and contraction is 24% and 50% less than aluminum and steel,  providing greater dimensional stability.
(3).Durability:Superior durability to Stainless Steel, Aluminum, and Galvanized gratings, especially in highly corrosive environment.
(4).Strength:50%higher tensile strength than hot rolled steel and better impact resistance.
2.Cutting method:
Serging four side,Serging three sides,Serging opposite sides,Serging the neighboring sides,Non-serginh.
3.Surface Treatment: Smooth surface grating,Concave surface grating, Microvoid grating, Sandy grating,Cover board gratin,Transparent grating
a)Smooth surface and italic grid make it easy to clean.
b)Cross distributing loads equally to improve the bearing capacity.
c)Surface grooves prevent slipping, covered sand type is better in anti-slipping.
