Insulating and skidproof Staircase is created in adopting techniques of high temperature polymerization of pultruded FRP, assemblage technique of integral plunger. It has the stable modeling of isosceles trapezoid and skidproof design of strut pole and foot of staircase. So it is characterized by hollow structure, lesser weight and greater intensity, better elasticity, fatigue resistance, more security; at the same time, because of insulativity, it is also the same with special staircase for electrician. The pole and foot are made of hard rubber, having antifriction, weather ability, vivid color, unfading and corrosion resistance, so it can be applied in many fields.
