Welcome to inquire! Contact: Mr. Xu. High-frequency welding H-beam high-frequency current to the metal surface localized heating, the external force makes welded steel attic, do not use any wire, flux, continuous mass production. Advantages 1. High accuracy due to the cross-sectional dimension of high-quality steel coil, after an excellent cross-section shape precision welding, assembly make the structure easier. 2. Excellent performance section flange plate and web thickness ratio can be increased, and rolled steel phase than in the same weight can be made larger bending performance, higher performance components section; in the same section performance steel canopy, lighter components 3. sectional dimensions can be customized heavy use case. can be specified by the user metallographic cross-sectional dimensions of production. 4. welded parts of the web material properties of homogeneous tissue fusion uniform flange plate material. What is the Color of foam sandwich? Color Color foam sandwich by two volumes, also known as (steel tile) steel building, in the middle of ordinary foam, polystyrene, extruded polystyrene, polyurethane, polyester and wool three other components, has been steel pan for large industrial plants, warehouses and workshops steel, gymnasium, Color flow room, Color integrated housing, clean shop and the need insulation fire place. Color Volume is a sophisticated technology and steel complex mix of bright luster peritoneal synthetic one, no surface decoration, color steel coil coating retention period of 10-15 years. Color foam sandwich beautiful shape, luster bright, the overall effect is good, insulation resistance, fireproof, waterproof effect, color steel sandwich panels with foam without having to re-decoration, quick installation convenient, short construction period, is a versatile extensive, very high potential of green building materials.
