W strip mine support strip steel W-beam roof with steel manufacturers Mine W W W strip steel strip with a price ceiling strip uses W W W steel strip advantages of high quality steel roof models strip W W W strip steel band, also called W-shaped steel belt or steel roof, its cross-section like the letter "W" and the name. W steel bolt action is bolting together to form grid, or play a coal mine tunnel wall support (slope) of the role of engineering tunnel wall. W strip Yangquan Coal will comprehensively promote the business planning and Shanxi "Thirteen Five" power planning convergence work. Standing in line "Thirteen Five", into Shanxi Energy large base to ensure that the total installed capacity of 5 million kilowatts of power height three to five years, to seize the inter-provincial cooperation, industrial transfer of the favorable opportunity, W steel in accordance with the first market, after reverse thinking of projects, and actively looking for potential partners, W strip use UHV outgoing line scale construction and other favorable conditions, W power strip to accelerate the delivery point outside the Group W strip preliminary project forward speed. W strip Uses: W is a new strip mine supporting material, W steel with a thickness of 3-5mm width 180-320mm rolled steel, after cold-formed steel belt after a W, W strip in the middle of working out and W steel anchor bolt spacing equal to the hole. W strips together with a variety of combinations of various bolt anchor plate bracket, W W steel strip that is scattered by a plurality of bolts banded together to form a whole load-bearing structures, W steel is widely used in coal mine roadway, work Cut surface, caverns and other areas roadway, better handling of instability surrounding rock. W strip parameters: Expand the width (MM) 180mm 200mm 220mm, 250mm 280mm, 300mmw W strip thickness (MM) The main advantage of 2.5mm 2.75mm 3.0mm W w steel strip: 1.w strip according to different geological conditions and operating environment model selection. 2.w steel bending section modulus increase 37-fold down section modulus of about upward section modulus of 2.75 times, so when installing, using bolt rig up top tight. 3.w strips than with other types of steel, W steel is more difficult to tear, and steel degree, increased by about 70 times. 4.w hardened steel cold rolling process, and improve the tensile strength of 12% -15%. 5.w section steel utilization, saving materials, low prices. 6.W steel with lower support costs, saving support steel and other advantages.
