Metal Cladding System

The metal cladding system includes wall cladding, roof cladding, skylight sheet, flashing and trim, gutter as well as insulation materials. They are essential components of steel structure building, which determines the appearance, waterproof, and thermal insulation of the building.

Metal Cladding System

The components of Metal Cladding System

Metal cladding system include Corrugated Metal Sheet, Glass Wool Insulation, Skylight Sheet, EPS sandwich panel, Glass Wool/Rock Wool Sandwich Panel and Polyurethane (PU) Sandwich Panel.

Corrugated Metal Sheet	Steel Building Insulation	daylighting panel
Corrugated Metal Sheet Corrugated Metal Sheet is the steel plate with organic coating, which has the advantage of corrosion resistance, beautiful appearance, convenient processing and forming, it has the original strength of the steel plate and lower cost.	Insulation Insulation cotton is used for coils made for large-area laying. In addition to maintaining the characteristics of heat insulation, it also has excellent shock absorption and sound absorption characteristics.	Daylighting Panel The daylighting panel can lay from the roof ridge to the eave, parallel to the gable wall, which provides sufficient natural light for the interior, and does not affect the drainage of the metal roof panel.
glass wool sandwich panel	EPS Sandwich Panel	PU Sandwich panel
Glass wool sandwich panel Glass wool is an excellent inorganic insulation material. The prominent characteristics of glass wool are excellent fire resistance, high flame retardancy, and moisture absorption, and its price is low. The thermal conductivity of the glass wool sandwich panel is not more than 0.038 W / (m2 • K).	Polystyrene (EPS) sandwich panel Polystyrene is a material with polystyrene resin as the primary raw material, which is made of foaming agent and has numerous closed micropores inside. The price is low, and the strength is slightly worse. The thermal conductivity is not higher than 0.038W / (m2 • K).	Polyurethane (PU) sandwich panel Polyurethane sandwich panel has a thermal conductivity of not more than 0.033 W / (m2 • K), has excellent thermal insulation performance, excellent water resistance, high strength, foam can be made into any shape, and is suitable for field construction.

Trim and Flashing for Metal Cladding System

The trim and flashing used for waterproofing. Generally refers to the colored metal sheet bending parts at the door, window, corner, eaves, canopy and other parts of steel structure buildings

Wall Corner Trim

The Wall corner trim is placed at the corners of the exterior walls of the metal building to cover the joints where the sidewalls and the end wall panels meet for waterproofing and decoration.

Wall Corner Trim

Gutter

The gutter is an essential component of the roof drainage system, which is used to collect rainwater and drain it through the downspout temporarily. The overlap of the gutter is 100mm, and rivets connect the overlap.

Gutter classification:
1. steel plate.
2. galvanized plate.
3. stainless steel.
4. metal color sheet.

Gutter

Roof Ridge Cap

The metal ridge trim is at the highest point of the ridge, where the two roof panels overlap, the trim arranged along the hill, where the two ribs intersect.
The ridge trim cap is erects after the roof panel finishes installing.

Roof Ridge Cap

Gable Trim

The angle of the gable trim matches the slope of the gable roof and covers the joint formed by the intersection of the roof panel and the end wall panel on the steel building, and there is no overhang at the roofline.

The combination of the gable trim and sealant provides a waterproof seal for your roof system.

Base Trim

The base trim is a barrier between the bottom of the exterior wall cladding and the foundation. Angle steel bolted to the edge of the concrete floor. The base trim is connected to the angle steel, forming a ledge under the exterior wall panel.

The Base trim uses to prevent the bottom of the wall panel from contacting the concrete slab and protect the metal sheet, and
cover the irregularities of the foundation edges to make the foundation edges more neat and beautiful

Base Trim

Wall Corner Trim

The Wall corner trim placed at the exterior walls corners of the metal building to cover the joints where the sidewalls and the end wall panels meet for waterproof and decoration.

Wall Corner Trim

Gutter at Overhang

The gutter at overhang is connected with the roof panel, with the wall panel as the dividing line, the one associated with the cantilever beam, and the beam’s outer edge as the dividing line. The overhanging gutter is outside the edge of the external wall or the edge of the beam.

Gutter classification:
1. steel plate.
2. galvanized plate.
3. stainless steel.
4. metal color sheet.

Metal Cladding System-Corrugated Color Metal Sheet

The composition of corrugated color metal sheet:

The color metal sheet is generally composed of base sheet + aluminum-zinc or galvanized + color coating.

metal sheet1. Base sheet
The base sheet material ranges from a yield strength of 300Mpa to 550Mpa, and a thickness from 0.3mm to 0.8mm.

2. Aluminum-zinc or galvanized

There are two types of anti-corrosion coatings: aluminum-zinc (55% aluminum) and galvanized. Among them, aluminum-zinc sheet has better anti-corrosion performance. Therefore, if used for roof panels, it does not need to be overlaid with color coating, and the original color of aluminum-zinc plating can be used directly. Of course, the color coating can also be added to the aluminum-zinc sheet; the anti-corrosion performance of galvanizing is slightly worse. But because aluminum is expensive, zinc is cheap, and the amount of galvanized coating is increased, it is also a good choice for the anti-corrosion performance of color-coated color steel sheets.

3. Coating types

1). Types of finish

Polyester (PE)

Silicon modified polyester (SMP)
High Weather Resistance Polyester (HDP)
KYNAR@500: Contains 70% polyvinylidene fluoride (PVDF)

2). Types of primer
Epoxy resin (EP, EPoxy resin)
Polyester (PE, PolyEster)
Polyurethane (PU, PolyUrethane)
