The FRP guardrail series is made of FRP pultruded profiles through a certain assembly process. The glass steel guardrail series includes four types: standard square type, economic type, standard round type, and heightened type. The type of profile and the installation distance, height, position, quantity, etc. can also be changed according to customer requirements. At the same time, the color can be selected according to customer requirements .
The pultrusion process is a mechanized composite material molding process in which reinforcement materials such as non-twisted glass fiber roving and glass fiber mat are impregnated with resin through a resin bath under the traction of a pultrusion machine, and then heated and shaped by a forming mold to produce a mechanized composite material molding process. FRP guardrails have most of the characteristics of guardrails, but there are also significant differences. FRP guardrails are light in weight and easy to install without welding. FRP guardrails have strong corrosion resistance and will not rust. Long-term use does not require maintenance to reduce costs. The FRP guardrail is bright and beautiful in color, and it does not need external decoration to form a scene on its own.
FRP guardrails are assembled from pultruded profiles. It is widely used in petrochemical industry, sewage treatment, thermal power generation, traffic roads, river banks, lakesides, courtyards, villa communities, fences, gardens and other places.
Features of FRP guardrail:
1. High strength and impact resistance: similar to the strength of steel, four times that of ordinary plastics, impact resistance and easy recovery, large elasticity after being hit by objects, and can be restored to the original shape. The tensile and bending strength is more than 600pa, and the tensile capacity is about It is 50 times that of steel.
2. Corrosion resistance, it will not be affected by the long-term action of 10% sulfuric acid, 20% nitric acid, and 50% acetic acid. No maintenance, no rust, no need to paint every year, basically no maintenance fee.
3. Good weather resistance, no oxidation and corrosion in hot and humid conditions, no fading, no paint protection, no daily care, no fear of lightning strikes. It is also different from wood and other materials that will rot and mildew.
4. Variety of colors and soft color: Like plastic, it can have a variety of colors, which is convenient for urban color design and does not have the reflective pollution of stainless steel.
5. Lightweight and easy to install: the specific gravity is only 1/4 of steel, which is convenient for installation and construction.
6. Anti-theft: As FRP cannot be recycled and sold, the possibility of theft by criminals is reduced.
Can be customized according to customer requirements.
The basic composition of FRP guardrail:
The frame structure is based on a glass fiber reinforced plastic square tube or a round tube, uses a glass fiber reinforced plastic grating as the main protective surface, and then uses various connectors to connect the various parts together.
FRP guardrail has smooth surface, delicate hand feeling, bright color, high strength, good toughness, and the resistance test can reach 50 years. No fading, cracking, and embrittlement when used at -50°C to 70°C. The unique formula and special stabilizer ensure that the appearance is long and new, not faded, not yellowing, not brittle in winter, not soft in summer, without painting, maintenance, and maintenance, and the service life is as long as 30 years.
