Spec construction elevator floor elevator doors protective doors composed entirely of steel. Steel using the national standard materials, produced strictly according to the drawings, the correct size, weld firm, reached safety purpose indoor elevator security doors, construction elevator shaft protective door price, entrance security door manufacturers elevator shaft protective doors of the elevator shaft protective door elevator Well protective doors protective doors of the elevator shaft of the elevator shaft elevator doors wellhead protection protective doors capacity, installation and production of standard bearing capacity of the elevator doors wellhead protection requirements: Protective door at 1kn horizontal force should be no damage, the bar should be less than equal to the maximum degree of disturbance 10mm. Wellhead Protection elevator door installation requirements: safety warning color spray should be correct, standardize, bolting should be firm, not loose, doors open and flexible, open and reliable fixed state. Wellhead Protection elevator door production requirements: component dimensions, specifications shall comply with the requirements of Atlas, protective door height is greater than equal to 1.4m, the material thickness of member shall be greater than or equal 2mm, the main carrier member material wall thickness deviation 0.3mm, protective door for diagonal length is less than equal to 5mm, clear spacing between the bars should be less than equal to 150mm, not tainted seam welding, cracks and holes and other defects, surface paint coating should be seamless, falling, cracks, wrinkles and bubbles and other defects. Lift the protective door is construction site injury prevention necessary protective equipment, which applies to all types of building construction site. Features Production Method: elevator door protection composed entirely of steel. National standard steel materials, production strictly according to the drawings, the correct size, weld firm, to achieve the purpose of security, elevator safety door with lemon yellow, the Ministry of the stall door plate with yellow, black interval. Doorframe usually Baosteel 20mm * 30mm square pipe welded together knot can also be customized according to customer requirements 20 * 20, 25 * 25, 30 * 30, 30 * 40 square and rectangular tube. Using welding knot, high strength, stable quality, strong throw, twist not sealing off. The latch bolt galvanized complete process, appearance, ease of use. Bolt design on the outside, only the switch by the elevator operator protective doors, effectively prevent the protective door open floor waiting staff, eliminate the potential risks of construction and high-altitude aerial parabolic fall. Facade holes using a combination of steel mesh or welded wire mesh and steel plate. One can prevent the wait staff to reach out to open the door, but also to facilitate people and goods elevator operator to observe the situation in the building, both inside and outside the two sides is conducive to building staff communication. High-strength cold-rolled steel material is also widely used by small cars can fight more than 300kg of impact, effective prevention plays a personal security construction elevator and floor platforms. And spray warnings and warning lines foot block of civilization construction site image significantly. Door shaft # 16 knot made pipe welding, greatly simplifying the installation program, just outside the door on the frame steel pole axis corresponding to the position of the welding 90 degree angle bar, the protective door hung either use, disassembly also convenience.
