Multiple Opening EN124 B125 Rectangular Manhole Cover
Composite Telecom Manhole Cover, three models:single opening, double opening and triple opening, to meet different project requirements.
Outstanding Features of SMC Manhole Covers:
① SMC manhole covers have smooth and beautiful appearance, with many optional colors (black, gray, green, yellow, red). The cover surface is designed to be anti-skid and with delicate patterns and lines, product surface can be customized design.
② Lightweight. The weight of glass reinforced plastic manhole cover is 1/3 that of a cast iron manhole cover or cement manhole cover. So that SMC manhole cover is easy for one man operation, more convenient for daily inspection and maintenance, also can reduce the risk of labor injury.
③ These Rectangular SMC Manhole Cover are with excellent toughness and not easy to crack or break. The load bearing capacity can be graded up to standard of EN 124-1:2015, EN 124-5:2015.
④ Anti-corrosion and anti-aging, resistant to any harsh weather conditions. The properties of the fiberglass themselves give the products excellent high and low temperature resistance (the products can be used at -50~160℃), chemical resistance (acid, alkali, salt, organic solvent, etc.) and dimensional stability (very low coefficient of thermal expansion: 12*10-6/℃).
⑤ Compared to metal, the SMC material is with remarkable insulation and excellent dielectric performance. Through the improvement of the formula so that the product has excellent anti-static performance and fully meet the electronic industry SJ/T11159-1998 floor covering and assembly floor electrostatic performance requirements. Also, composite material is non-rusty, no scrap value and less noise.
⑥ Long service life. Through the use of high performance resin, glass fiber and special production process formula, to ensure the resin penetration in glass fiber, greatly enhance the internal adhesion, so that the product has a high fatigue strength, under the action of a given effective load and frequency, its service life is usually not less than 30 years.
⑦ Environmental-friendly. The raw materials used are halogen-free, SMC is non-toxic products. The reasonable structural design solves the noise problem caused by the impact between the cover and the frame.
⑧ Compared with cast iron manhole covers, the uultiple opening manhole cover is a material that penetrates electromagnetic waves almost without changing the properties (including energy) of electromagnetic waves, so it can be widely used in the telecommunication industry.
