Metal Roof Panels

Metal roof panels use metal sheets as roof material, and the structural and waterproof layers are combined into one roof form. There are many types of metal sheets, galvanized steel sheets, galvalume steel sheets, stainless steel sheets, etc. The surface of the plate can be painted, mainly PE, SMP, HDP, and PVDF these four kinds of paint treatments, baking paint can strengthen the service life of the plate. They are 5-8 years, 10-15 years, 15-20 years, 20-25 years or more. Follow me to get more details.

Metal Roof Paints

Polyester (PE)

PE: Good adhesion, rich color, low cost. The advantages of PE polyester color-coated board are mainly cost-effective, and PE paint is recommended in a more friendly environment.

High Durability Polyester (HDP)

HDP: Excellent color retention and UV resistance, excellent outdoor durability and powder resistance, rich color, and cost-effectiveness. The most suitable environment for HDP is a harsh weather environment, such as the plateau and other areas with strong ultraviolet light. We will recommend customers to use HDP.

Silicon-modified Polyester (SMP)

SMP: Good external durability and resistance to pulverization, gloss retention, and medium cost. SMP is suitable for use in high-temperature factory buildings, such as steel mills and other indoor high-temperature environments is generally recommended to use SMP.

Polyvinylidene Fluoride (PVDF)

PVDF: Strong UV resistance, dirt resistance, not easy to fade, but limited color, high cost. Many plants with strong corrosive environments will choose to use PVDF paint.

Metal Roof Panels Features

1. Strong durability. Metal roof panels have extremely high durability and can maintain stable performance under various adverse weather conditions.
2. Good fire performance. Metal roof panels are not easy to burn, and can effectively resist the spread of fire.
3. Corrosion-resistant. Metal roof panels are not easily affected by corrosion and can be used in a humid environment for a long time.
4. Easy installation. The installation process of metal roof panels is simple and convenient, and the roof covering can be quickly completed.
5. Lightweight design. The material of metal roof panels is light, which can reduce the weight of the entire building and is conducive to the structural design of the building.

How to Install Metal Roofing?

1. Before installation, measure and design the roof panels to determine the size and quantity of the roof panels.
2. The choice of materials according to the different uses of the environment, to choose different metal materials to ensure the durability of the roof panel.
3. In the installation process, first install the skeleton of the roof panels, and then install the roof panels one by one for sealing treatment. The installation process must strictly comply with the design requirements.
4. Maintenance: Regular cleaning and maintenance to maintain the appearance and performance of the roof panel.

The Difference Between Roof Panels And Floor Panels

1. The difference in thickness position

The floor panel is indoor, and most of the floor thickness is 80-160mm, the biggest function of the floor panel is to bear weight, and there are differences in the plate thickness and the type and density of reinforced steel bars. The roof panel is outdoor, and the thickness of the roof floor is generally 60-80mm, which has great requirements for waterproofing and thermal insulation.

2. Functional differences

The main function of the roof panel is to form the enclosure space of the building with the wall and the ground and play the role of heat preservation and insulation, weatherproof and sun-proof, waterproof, and so on. The main function of the floor panel is to vertically divide the space within the building.

3. The difference in structural bearing

From the structural bearing, the roof plate mainly bears a load of plate weight, suspended ceiling, leveling layer, insulation layer, waterproof layer, snow, ash accumulation, maintenance, and other loads, and its load composition is mainly permanent load. The floor panel mainly bears the load of self-weight, plastering, resident furniture, etc. In addition to the self-weight of the civil building, the live load is the main load. So the proportion of live load on the floor is higher.
