Steel structural construction systems are mainly composed of two parts: the main steel structure system and the steel cladding system.

The steel cladding system is used to resist environmental adverse effects (also including some accessories).

According to the position in the building, the steel cladding system is divided into an external cladding system and an internal steel cladding system. The outer steel cladding system includes exterior walls, roofs, windows, external doors, etc., which are used to resist wind and rain, temperature changes, solar radiation, etc., should have thermal insulation, insulation, sound insulation, waterproof, moisture-proof, fire, durability. The inner steel cladding system is such as partitions, floors and interior windows, and the indoor spatial effect should have sound incenses, obeys, and certain specific requirements. The steel cladding system is usually referred to as an external steel cladding system such as the outer wall and the roof.

The components of the Metal Cladding System

Corrugated Metal Sheet

Corrugated Metal Sheet, is color coated steel plate, and cold-bended into a variety of shapes. It is suitable for industrial and civilian buildings, warehouses, large-span steel structural buildings, internal and external wall decorations,  it has the original strength of the steel plate and lower cost. Now it is very popular.

Technical feature:

  1. Corrosion Resistance
  2. Strong Strength
  3. Aging Resistance
  4. Chalking Resistance
  5. Self-cleaning
  6. Yellowish Resistance
  7. Cheaper Maintenance
  8. Excellent Performance

Insulation

Use color steel plates and insulation cotton. First lay a layer of insulation cotton material in the roof, then install the color steel plate. Steel structure roof insulation cotton, commonly used glass wool-cotton material, roof thermal insulation effect is very good, and it is also a more popular steel structure building, plant greenhouse and other roofing procurement.

Rock Wool Sandwich Panel

Sandwich board is a common product in the current building materials, which is not only good to flame retardation but also environmentally efficient. The sandwich panel is compressed by the upper and lower metal plates and the insulating internal material. It has the characteristics of easy installation, and high quality and environmental protection. Depending on the internal core material, it can be divided into EPS, Rock wool, glass wool, polyurethane sandwich plate. Rockwool Sandwich Panel Has Class A fireproof level, has good adiabatic performance, excellent sound insulation and sound absorption performance. It generally can be used for building external wall insulation.

Polystyrene (EPS) Sandwich Panel

The Polystyrene (EPS) Sandwich Panel is beautiful, the color is bright, the overall effect is good, the weight is light, heat preservation, waterproof, and does not need the secondary decoration, it is a wide range of uses, especially for the construction site, such as the office, warehouse, the wall, etc., especially in the use of rapid installation, there is an obvious advantage, and the cost is low. Scope of application: workshop, office partition wall, steel structure room exterior wall maintenance, decorative building materials, prefab house building, etc.

Fire Level: B3 (not fireproof).

Polyurethane (PU) sandwich panel

Polyurethane sandwich panel, also known as PU sandwich plate. This product is made of polyurethane foam as core insulation material and pressed by two metal panels, which is usually used in industrial plants, logistics warehousing, wall surface, roof enclosure system. The combustion performance of the polyurethane sandwich panel reaches B1, and the valid width of the sheet is usually 1000 mm, which also can be customized. The production of the polyurethane sandwich panel requires the advanced sandwich panel continuous production line, the process is the internal and external galvanized ( or Aluminized zinc) colored steel plate cold bending, intermediate coated polyurethane. The anti-leakage sandwich house panel is made by patented technology, and the advantages of the polyurethane sandwich panel are used to ultimate.

The PU sandwich panel has the following features:

How is Metal Cladding Installed?

Metal cladding system can be laid vertically, horizontally to meet your requirements, and is even capable of being applied to curved facades and a variety of unusual shapes. It’s available in a range of corrugated and other profiles, or can be laid flat as part of a panelized installation for an ultra-modern effect.

The Importance of Steel Cladding System

The cladding system not only maintains the warmth of the factory but also has an aesthetically look. According to the experience of construction, we must pay attention to the installation of the cladding system of the steel structure building. If the cladding system is guaranteed by the steel structure building, the sandwich panel or other enclosure material is the basis for the guarantee.
