1、 Fiberglass grating is resistant to corrosion from various gas and liquid media such as acid, alkali, organic solvents, and salts. Fiberglass grating has incomparable advantages in the field of anti-corrosion. It will not undergo electrochemical corrosion and rust under the action of chemical media, and will not cause damage to the structure of the material. It does not require regular or irregular inspection and maintenance. It is also different from wood and other materials that may decay and mold. It is an upgraded product of traditional materials such as iron, wood, and cement. According to the requirements of actual usage scenarios, resins such as ortho benzene, meta benzene, and vinyl can be economically selected as matrix materials.
2、 Fiberglass grating is lightweight and high-strength. Fiberglass grating is composed of resin and fiberglass, with a lower density. Compared with steel grating, the density of fiberglass grating is only 1/4 of steel and 2/3 of aluminum, while its strength is 10 times that of rigid polyvinyl chloride. Its absolute strength exceeds that of aluminum, reaching the level of ordinary steel. Its lightweight can greatly reduce the foundation support and material costs of the project. It is easy to cut and install, without the need for hot work or large lifting equipment, and only requires a small amount of manual labor and electric tools, greatly reducing installation costs.
3、 Fiberglass grating has high flame retardant and fire safety. The oxygen index (tested according to GB 8924) of general fiberglass molded grilles is above 32, and the flame propagation rate (tested according to ASTME-84) is flame retardant level 1; The flame propagation rate of high flame retardant vinyl grating reaches below 10 and is recognized by the American Bureau of Shipping (ABS).
4、 Fiberglass grating has higher impact and fatigue resistance than other materials. Fiberglass grating has high impact strength, allowing for repeated bending without permanent deformation, while metal grating retains permanent deformation after being impacted and needs to be repaired. Fiberglass grilles have moderate elasticity, making people who work on them comfortable for a long time, reducing the sense of urgency on their legs and back, reducing the occurrence of accidents, and improving production efficiency.
5、 Fiberglass grating has good anti slip performance. Fiberglass reinforced plastic grilles have anti slip function. Fiberglass reinforced plastic grilles formed by molding have two types: naturally formed anti slip concave crescent surfaces and anti slip sand surfaces. The anti slip sand surface also has two types: integrated molding with sand inside the mold and re processing with adhesive after demolding. Both types of sand surfaces provide superior anti slip function, and the sand layer is not easy to peel off, making it durable. The use of fiberglass grilles makes walking safer and more comfortable, greatly reducing the occurrence of accidents caused by personnel slipping.
6、 Fiberglass grating is aging resistant, aesthetically pleasing, and easy to maintain. The fiberglass grating is made of high-quality resin and fiberglass system, ensuring a service life of over 20 years. According to the research and testing of the aging performance of FRP products by the National Research Institute, the results show that glass fiber reinforced resin products treated with specialized glass fiber infiltration can still maintain strength above 85% after 20 years of atmospheric exposure.? Fiberglass grating is made by blending color paste into all resins. It has a bright color, is not easy to fade, does not require paint, and is not limited to the surface like paint. The smooth surface filled with resin and the sloping inner surface make the grating self-cleaning. Even if there is dirt, it is easy to rinse with water or detergent, making the surface of the grating smooth and new.
7、 Fiberglass grating has high electrical insulation safety. Fiberglass grating has excellent electrical insulation and no breakdown or arcing phenomenon at a voltage of 10KV. It is used in areas with conductive hazards such as work platforms, floors, and fences to reduce the harm to workers caused by electric shock in conductive areas and around switchgear; Has no electromagnetic properties and can be used on devices sensitive to magnetism; Without electric sparks, the use of fiberglass grilles avoids the danger of explosions and fires caused by tools falling on metal grilles in flammable and explosive places.
8、 Fiberglass grilles are easy to install. The use of FRP grilles greatly reduces the weight of components, thereby reducing the weight of supporting structures. There is no need for lifting equipment during installation, which is both economical and convenient.
9、 Fiberglass grating has low cost and high comprehensive economic benefits. The manufacturing cost of fiberglass grating is 1.4-1.8 times that of steel grating, and the installation cost is only 20-40% of carbon steel. The maintenance cost of fiberglass grating is almost zero, but it needs to be maintained every year, and the accumulated maintenance cost greatly exceeds the total cost of fiberglass grating. Although the initial investment cost of fiberglass grating is slightly higher than that of steel grating, the overall economic benefits are 4-5 times that of steel grating, which is one of the main reasons for the widespread use of fiberglass grating abroad.
