As the ancillary facilities of the city inspection shaft, for a long time, the ladder material has been made of steel. However, under many harsh environmental conditions, such as inspection wells, tunnels, chemical enterprises, rainy and humid occasions, the traditional metal ladder is very easy to rust, which affects the safety of use and has a short service life.

Details Introduction


As the ancillary facilities of the city inspection shaft, for a long time, the ladder material has been made of steel. However, under many harsh environmental conditions, such as inspection wells, tunnels, chemical enterprises, rainy and humid occasions, the traditional metal ladder is very easy to rust, which affects the safety of use and has a short service life.

Basic performance

Glass fiber reinforced thermosetting composite materials are mainly composed of glass fiber which plays a reinforcing role and thermosetting resin which plays a bonding role and transmits load. The tensile strength of glass fiber is very high (3450mpa), and its content, length, and laying form determine the strength of the product. The thermoset glass fiber reinforced composite strength may be in the range of 30-1000mpa. Therefore, we design the amount, length and laying form of glass fiber according to the product's stress, output, production process, and price tolerance.

The rigidity of glass fiber reinforced thermosetting composite ladder is doubled compared with other fiber reinforced materials, and it does not deform even under long-term load.

Glass fiber reinforced thermosetting composite ladder is corrosion resistant, acid and alkali resistant, especially suitable for use in humid, salt spray, acid and weak alkali environments.

Through the embedded installation directly into the wall, the positioning is accurate and firm, the construction is very convenient.

The anti-aging index of the product can reach above grade 4 of the national standard, which basically meets the requirements of 50 years underground and 20 years above ground.
