How To Choose And Purchase Hot-Dip Galvanized Steel Grille Pedals

First of all, the metal stair treads ramp must be carefully selected. It must be made of Q235 or more materials, such as American Standard 36 or Q345. If the material of the platform steel grille ramp is second-best and lasts a long time, it will inevitably lead to safety hazards.

The inclination angle between the fixed steel ladder and the degree plane of the stepping ladder of hot-dip galvanized steel grid plate should be in the range of 25 85 and the optimum inclination angle should be 30. The maximum inclination of accidental entry should be 42 degrees. The maximum inclination angle of the regular two-way traffic should be 38 degrees.

Welding connection shall be adopted for metal stair treads ladder steel ladder. Welding request shall conform to relevant national rules. When joining in other ways, the bonding strength should be no less than that of welding. The ladder after the installation should not be inclined, distorted, deformed and other defects.

Secondly, hot-dip galvanized steel grille pedal ramp has special requirements in anti-corrosion and anti-rust. Because most of the hot-dip galvanized steel grille pedal ramps are used in heavy chemical and other places, according to the use of steel ramps and environmental conditions, appropriate anti-rust and anti-corrosion coating should be stopped for ladders. To reduce the corrosion and corrosion of the ladder, the fixed steel ladder device should keep the moisture minimum.

Finally, there is a big problem that needs to be noted for the metal stair treads ramp. Platform steel grille pedals shall be provided with anti-skid data or at least with anti-skid flanges not less than 25 mm wide. The pattern steel plate with thickness not less than 4 mm, or the common steel plate with anti-skid treatment, such as the square tooth plate, should be used.
