How To Age Steel Panels?

Steel Glasswool Panel

Is made up of two layers of color-coated steel plates as the core, and the thermal insulation materials such as polystyrene, polyurethane, phenolic foam, rock wool, etc. Are core materials, and are continuously formed on a dedicated automated production line. The process combines the core material and the panel into a whole building board, commonly known as a “sandwich board”. Although the composite sheet has been introduced into china for less than 20 years, it has been widely recognized and used in the clean room of the building due to its series of advantages such as bearing capacity, thermal insulation, decoration, waterproofing and simple construction. It has challenged traditional building materials such as masonry and has become a new army in the building materials industry.


First, metal siding  and performance comparison

    color steel sandwich core material can be divided into two categories according to the chemical composition of its products, that is, organic chemical foam materials, such as polystyrene foam eps, polyurethane foam pu, extruded polystyrene foam xps, phenolic foam pf, etc.; the other type is inorganic fiber materials, such as rock wool board, foamed cement board, and the like.

1, polyurethane foam metal roof panels l pu

    the polyurethane foam color steel sandwich panel is made of a flame-retardant rigid polyurethane foam as a core material, and a color coated steel sheet as a surface material. At present, domestic metal surface rigid polyurethane sandwich panels are widely used in industrial plants, warehouses, stadiums, residential houses, villas, movable board houses, combined cold storages, etc., but the disadvantages are that under the conditions of high temperature and alkali reaction, the equipment requirements are high, the initial investment is large, and industrialization is difficult.

2, polystyrene foam color steel sandwich panel eps

polystyrene is the white foam we often see. This color steel plate is cheap, water-resistant and non-deformable. Most of the mobile homes on the construction site are built with polystyrene sandwich panels, which are widely used but polystyrene foam. The sandwich panel is not fireproof and has the worst insulation effect.
