There is a wide range of rigid conduits: rigid metal that are made by hot dip galvanized method and stainless steel as well as accessories. The rigid plain-wall hot dip galvanized steel conduits producing by Sendzimir method are ahead of mechanical strength and industrial conditions, where is necessary to have a reliable protection of mechanic and other aggressive influence. The rigid conduits are also good for wiring inside inflammable bases, wooden houses and reconstruction of inflammable floors, attic or cellars. The rigid stainless steel AISI 304 and AISI 316L properties is distinguished by high corrosion resistance and used in chemically aggressive environments in food, metallurgical, chemical and pharmaceutical industries. The inner seam welding is removed for well-sliding cable broach. The accessories are produced by patented technology and provided easy fitting.
