Amount of stretching SGF120 SGF120 bridge expansion joints bridge expansion joints is 0 ~ 120mm, ranged between 80mm and 160mm telescopic volume, use expansion joints to avoid stretching the amount of 80mm telescopic device is caused by traffic is not smooth, and the amount of telescopic 160mm expansion joints and increase project cost issues. SGF120 bridge expansion extrusion molding Q345 (ASTM A709 Grade50) steel manufacturing, with high strength. Steel for the tooth structure, increasing the amount of stretching, improve the smooth road for highway and urban road bridge expansion joints, and can better adapt to the longitudinal displacement of the bridge. This product uses the anchoring system expansion joints and GQF-MZLⅡ80 same end for a variety of beam structure, which reserved slots (including pavement) Height ≥150mm. The W-type neoprene elastic sealing strip embedded in the steel, waterproof, good dustproof performance. If the expansion joint surface corrosion using hot dip galvanizing process, corrosion and long life. We produce bridge expansion in the factory overall positioning assembly, easy installation on site. The company operating the bridge bearings, bridge expansion joints, 80 joints, 160 road and bridge expansion joints and other articles of bridge bearings factory Wei Xin Hengshui Rubber Co., Ltd.
