FACTORY ROOFING: COMMON TYPES AND HEAT RESISTANCE ABILITY
Roofing sheets are an indispensable material in the construction of industrial factories, widely used thanks to their superiority in light weight, fast construction and reasonable cost. However, depending on the type of roofing sheets and production technology, the heat resistance of the roofing sheets will be different, directly affecting the working environment inside the factory as well as the efficiency of equipment operation.
This article will help you understand the popular types of roofing sheets today and the insulation and heat resistance of each type, thereby choosing the most suitable solution for your project. Let's refer to the article below with Hung Nghiep Phu Construction Investment Company Limited!
1. Overview of factory roofing sheets
Roofing sheets are usually thin metal sheets, rolled into different shapes or patterns to increase load-bearing capacity and aesthetics. The basic materials are usually galvanized steel, galvanized steel or aluminum, with an additional protective paint layer on the outside.
Advantages of roofing sheets:
- Light weight, reducing the load on the factory structure;
- Fast construction, easy installation;
- Reasonable material and construction costs compared to traditional roofs such as concrete or tiles;
- Relatively high corrosion resistance and durability if properly maintained.
2. Popular types of roofing sheets and their characteristics
2.1 Cold rolled steel (galvanized or aluminum zinc coated steel)
- Material: Galvanized steel or zinc-aluminum, can be powder coated or painted
- Features: Low cost, light weight, resistant to common corrosion
- Heat resistance: Medium, cold-rolled steel absorbs heat quickly because the color is usually light or original metal; without additional insulation, the temperature inside the factory can easily increase in the summer.
2.2 Color coated steel (color coated cold rolled steel)
- Material: Cold-rolled steel coated with a variety of color paint shades
- Features: Increase aesthetics, diverse color options to suit brand identity or architectural requirements
- Heat resistance: Light colors such as white, light blue have better heat reflection ability, reducing heat absorption compared to dark colors. However, it is still necessary to combine additional insulation solutions to achieve high efficiency.
2.3 Insulated corrugated iron (PU foam corrugated iron or glass wool corrugated iron)
- Material: Galvanized or aluminum-zinc sheet with an additional layer of insulation underneath using PU (polyurethane) or glass wool;
- Features: Increases insulation capacity, keeps the internal temperature stable, reduces heat transfer from the roof to the factory;
- Heat resistance: Very good, helps reduce the temperature inside the factory by 5-10 degrees Celsius or more depending on the thickness of the insulation layer and construction technology.
2.4 Flat corrugated iron (square corrugated iron or round corrugated iron)
- Material: Corrugated iron sheets are rolled into many different styles to increase hardness and aesthetics;
- Features: Easy to install, good resistance to wind and rain;
- Heat resistance: Similar to cold-rolled or colored iron sheets, depending on the material and paint coating, without accompanying insulation layer.
3. Factors affecting the heat resistance of corrugated iron roofs
- Roofing color: Light colors have a higher ability to reflect sunlight, reducing heat absorption. Dark colors absorb more heat, increasing the roof temperature and the temperature inside the factory.
- Insulation layer under the roof: This is the most important factor to reduce heat transfer from the roof to the space below. Common insulation materials are PU, glass wool or heat-reflective membrane.
- Roof ventilation: A good ventilation system will help to release hot air accumulated on the roof, improving the temperature inside the factory.
- Roof thickness: Thicker roofs will have better insulation, but the cost and weight will also increase.
- Construction quality: Proper construction, ensuring joints, not allowing hot air to leak in will help optimize insulation capacity.
4. Choosing the right roofing sheet for your factory
The choice of roofing sheets should be based on the following factors:
- Purpose of the factory: If the production requires a stable temperature environment (such as food, electronics), heat-insulating sheets should be prioritized.
- Construction area climate: Hot and humid areas or harsh sunlight require sheets with high heat insulation and heat reflection capabilities.
- Investment budget: Cold-rolled and color-coated sheets are cheaper, suitable for simple factories; while heat-insulating sheets are more expensive but save long-term cooling costs.
- Aesthetics and brand recognition: Diverse color sheets make the project beautiful and suitable for architectural requirements.
Roofing sheets are a major factor in determining the operational efficiency, working conditions and maintenance costs of the factory. Understanding each type of sheet and its heat resistance will help investors choose the most suitable material for their actual needs, climate and budget.
