Stainless steel protective cover from steel or stainless steel cold-formed formed. For all types of machine tools to provide the appropriate type of protection rails (horizontal, vertical, diagonal, horizontal). According to different running speeds and rail steel shield structure is also different. Running speed 10m/min with us under the polyurethane or brass slider. Under medium speed 30m/min with rollers. Driver board, scraping plates between the need to use a buffer system, and to reduce collisions, noise and friction. Steel shield plates proportion, weight and operating characteristics are important. Every single section should be as long as possible, thus reducing the festival board, under normal circumstances the maximum tensile and minimum compression ratio should be between 3:1 and 5:1 (up to 10:1). Larger width must fold, increase lateral stability. Roof type and folding can be done, and tilting the liquid can flow away debris automatically.
