Mining unsaturated resin and fiberglass polymers pultrusion manufacturing process, material selection and epoxy resin combined with a pin technology, shaft steel work surface with protective coatings; insulating laminated type of material parts machined surface treated with a varnish. Ladder support, non-slip design fatigue foot of the ladder, ladder shape without sharp edges and corners of the components, the high degree of safety, strong insulation properties; low suction force, corrosion-resistant. Insulation ladder features: (1) non-conductive, the appearance of new, nice. (2) corrosion resistance (with acid and alkali resistance, salts, and many organic solvents and gas, corrosive liquid medium can, according to the actual use where required, can be economically choose to use O-type, phenylene-based, vinyl type resin matrix material), resistant to frail, fade-resistant. (3) Light weight, easy handling. (4) Low water absorption, flame retardant (common flame retardant grill flame spread rate (ASTM E-84) does not exceed 25; the flame propagation rate senior retardant vinyl grill does not exceed 10. The oxygen index of not less than 28 (GB 8924)). (5) high-strength, lightweight (FRP grating density is not greater than 2, only 1/4 of the steel, aluminum 2/3 to 10 times the strength of rigid PVC and absolute strength than aluminum and . level of ordinary steel (6) impact resistance, insulation resistance, permeability excellent insulation joints ladder specifications: 2M, 2.5M, 3M, 4M (can be customized according to customer demand) single lift Specifications: 3M - 12M (available according to customer demand) the word ladder insulation specifications: 1M, 1.5M, 2M, 2.5M, 3M (can be customized according to customer demand) Insulation single staircase Specifications: 2M, 2.5M, 3M, 4M (can be customized according to customer demand) Insulation ladder, extension ladder ultralight insulation, insulated pole ladder, multifunction overhaul frame, telescopic lift co-ladder, AC and DC lift, removable insulation lifting platform, quick-type insulation scaffolding crossbar full width:. 3.4cm vertical bar thickness: 0.6cm Weight: 2 m 5.75kg
