I plant the production of flat steel in accordance with gutter cover a certain distance between the vertical bar fight back only interspersed arrangement welded, and welding a steel cross defeat made goods with non-square grid next, it is important to work with a drain cover steel structure Chek platen, step ladders step on board. Normal take crossbar by twisting the bar. Usually Grating with ventilation, lighting, polyethylene cold, anti-astringent, explosion-proof performance. It can be used to increase the anti-tooth punch astringent properties. The method for producing trench cover are: welding machine with two welding by hand pressure. Application of low voltage resistance pressure welding machine pressure welder, robot take the initiative to set the bar at a flat, vertical, symmetrical arrangement, welding powerful crime rate through the power rails with hydraulic pressure into the inner flat bonding, but can lose the main welding point firmly, high stability of high moral character of war weak steel grating. Drain cover handmade steel grating non after punching in the flat, but will be placed into the hole West stanchion spot welding, steel rails take there will be gaps, and not whether it can stop each contact point are back welding pay, thus pay no welding firm, nothing weak degree of decline. 3, the template device according to measure discharge line, release template positioning device sideline, then where device template, kitchen drains cover plate, vertical template required. Not between the template and the template dislocation. 4, row cover application ditch ditch cover means preformed cover, kitchen gutter cover how to sell, played point after delivery pile. After draining ditches ditch body concrete construction, the front cover of the unit drain ditches, measuring class construction segment have been ranked ditch cover device substrate stop inspection, the kitchen gutter cover, to stop unqualified parts repair chisel or mortar, kitchen waste trench cover where the production, to ensure smooth discharge ditch cover of the unit base, fit the program requests elevation. Drain trench cover means smooth, not swinging. Friendship remind ditch cover construction machinery and materials should be placed in a uniform, fair deployment of the construction of electricity line, in favor of something a smooth stop.
