1. The installation cost of fiberglass grating stair treads is low
Because FRP grating is only 1/4 of carbon steel, it is very convenient to transport, lift, move and assemble, and does not require fire during installation. Therefore, there is no need to stop production in flammable and explosive areas, so its installation cost is only that of carbon steel. 20%~40%.
2. FRP grating stair treads have long service life
Under the allowed medium conditions, the design life of fiberglass grating can reach 20 years, while that of carbon steel is 3 to 5 years. Generally speaking, after ten years of use, the cost of using carbon steel grating will be more than double that of using fiberglass grating.
3. FRP grating stair treads do not require maintenance
Steel requires annual maintenance, while fiberglass grating is basically maintenance-free.
4. The base price of fiberglass grating stair treads is low
The quality of the FRP grating material determines the quality of the FRP grating. In other words, the composition and raw materials of the glass grating are the key factors that determine the quality of the FRP grating. The raw materials used in the production process of FRP grating include resin, fiberglass yarn, curing agent, color paste, etc.
Resin: Unsaturated polyester resin is a thermosetting resin that needs to be used together with fiberglass fibers. When reinforced with glass fibers, it can form a composite material, commonly known as "glass fiber reinforced plastics".
Glass fiber is a material used to strengthen fiberglass gratings. It has various varieties and has good insulation properties, strong heat resistance, good corrosion resistance, and high mechanical strength. It is made of glass balls or waste glass as raw materials, and is melted at high temperature. It is made by making, drawing, winding, weaving and other processes.
Curing agent, also called hardener, curing agent or stabilizer, is a type of substance or mixture that promotes or controls the curing reaction. Resin curing is an irreversible change process in thermosetting resin through chemical reactions such as condensation, ring closing, addition, and catalysis. Curing can be achieved by adding a curing agent.
Color paste is a semi-finished product made of pigments or pigments and fillers dispersed in paint. Oily slurries that use pure oil as a binder are called oily slurries. Using resin paint as a binder is called resin paste. The pigment and filler slurry prepared by using water as the medium and adding surfactant to disperse it is called water-soluble slurry. Because there are so many paints, there are many kinds of color pastes.
