There are many materials used to manufacture stair handrails, such as fiberglass materials, which are very good. So, what are the advantages of fiberglass handrails?
1. Good corrosion resistance
Fiberglass (FRP) is a composite material with good corrosion resistance. It has strong resistance to the oxidation of the atmosphere and water, as well as a variety of solvents such as acid and alkali salts with general concentrations. It has been used in environmental protection and chemical corrosion protection. It is gradually replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
2. Lightweight and high strength
The relative density is between 1.5 and 2.0, which is only 1/4 to 1/5 of that of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels, and other applications that require weight reduction. The tensile, flexural, and compressive strength of some epoxy FRP can reach more than 400Mpa.
3. Good insulation performance
Fiberglass is an excellent insulating material used to make insulators. It still protects good dielectric properties at high frequencies. It has good microwave permeability and has been widely used in radomes. FRP has low thermal conductivity, which is 1.25~1.67kJ/(m·h·K) at room temperature, which is only 1/100~1/1000 of that of metal. It is an excellent thermal insulation material. In the case of instantaneous ultra-high temperature, it is an ideal thermal protection and ablation resistant material, which can protect the spacecraft from the erosion of high-speed airflow above 2000 °C.
4. Can be designed flexibly
According to the needs, various structural FRP products can be flexibly designed to meet the requirements of use and have good integrity. The material can be fully selected to meet the performance of the product, such as corrosion resistance, instantaneous high-temperature resistance, special high strength in a certain direction of the product, good dielectric properties, etc. can be designed.
5. Excellent craftsmanship
The molding process can be flexibly selected according to the shape, technical requirements, application, and quantity of the product. The process is simple, it can be formed at one time, and the economic effect is outstanding, especially for products with complex shapes and a small number of products that are not easy to form, its technological superiority is more prominent.
The above is an introduction to the advantages of fiberglass handrail materials. The above is the introduction of the advantages of FRP handrails. This material is still very good and suitable for many industries.
