Introduction to metal roofing, what are the characteristics of metal roofing?

Metal roofing refers to a material made of sheet metal that is used as the roof of a building. The part of the building that uses metal roofing usually looks like it is paved with a layer of metal material, but in fact, the material made of metal roofing is not only metal material, but also in terms of basic metal materials, in order to be used to make metal roofing, it must also meet certain standards, and it is by no means ordinary metal can be made into metal roofing.

Metal roofing generally includes two parts: metal plate and coating, among them, there are many types of metal plates, mainly veneer and composite board, composite plate plate is between two metal plates to add a layer of insulation layer, the role in actual use is more prominent.

The specific content can be consulted Henan curtain metal materials, the company is a collection of material sales, metal roofing, wall engineering construction in one of the high-tech enterprises, the company is committed to the new steel structure of large span buildings, civil buildings to provide metal roofing, wall solutions, the first to introduce the world's advanced technology and production equipment from abroad, together with well-known domestic architects, structural experts, to provide customers with one-stop metal roofing, metal exterior wall energy-saving decoration integration system.

Answer: First, the characteristics of metal roofing.

1. The metal roofing system has good waterproof performance and fire performance, which greatly protects the building and has a high safety factor;

2. The metal roofing system has excellent structure, and it also has the advantages of light weight, strong durability, long service life and convenient installation;

3. The metal roofing system can show a unique personality and good decoration effect according to the flexible changes of the architectural shape;

4. Metal roofing materials are not only very environmentally friendly and energy-saving, but also have strong adaptability to buildings in different regions, environments and different functional requirements.

2. Factors to be considered in the design of metal roofs.

1. Load-bearing. Withstand construction loads, rainwater, dust, snow pressure, and maintenance loads.

2. Wind pressure resistance.

Resist the maximum local wind pressure, and the metal roof panel will not be pulled off by the negative wind pressure.

3. Sound insulation. Prevent sound from going from outside to inside or from inside to outside.

4. Anti-seepage. Prevents rainwater from seeping into the metal roof panels from the outside.

5. Lightning protection. Direct lightning to the ground to prevent lightning from penetrating the metal roof and entering the room.

6. Lighting. Save energy by improving indoor lighting during the day with skylights.

7. Safety device.

Set up fixed facilities on the metal roof to protect the safety of construction personnel and maintenance personnel.

8. Anti-icicles.

Prevents rain and snow from forming icicles at the cornice.

9. Beautiful. The exterior of the metal roof has a good texture and pleasing color.

10. Control thermal expansion and cold contraction.

Control the shrinkage, displacement and direction of the metal roof panel.

11. Keep warm.

Prevents heat transfer on both sides of the metal roof, making the indoor air temperature stable.

12. Sound absorption.

Reduces the reflection of sound and reduces the echo in the room.

13. Moisture-proof.

Prevent water vapor condensation in the bottom layer of the metal roof and the metal roof layer, and drain the water vapor in the metal roof layer.

14. Fire prevention.

In the event of a fire, the metal roofing material will not burn, and the flames will not penetrate the metal roofing panels.

15. Ventilation.

Air exchange takes place indoors and outdoors. Set up vents on the metal roof.

16. Anti-avalanche.

Snow railings are installed on the metal roof of the snowfall area to prevent the snow from sliding suddenly.

17. No pollution.

The metal roofing material will not produce environmental pollution, and there is no light staining on the surface of the metal roofing panel.

18. Normal service life.

The service life of the metal roof should be equivalent to that of the main building, such as 25 years, 50 years, 100 years.

19. Maintenance.

It is convenient for the maintenance of metal roofing during the service life and reduces maintenance costs.

20. Cost.

Control the construction cost of metal roofing.

No connectors, no screw holes, and the appearance of the building is complete.

It can be bent into an inner arc and an outer arc.

Different materials and colors can be selected.

The overall structural waterproofing and drainage function.

It can be used on roofs with small slopes.

Excellent wind pressure resistance (with the bottom plate), especially suitable for areas with many typhoons and storms, and can eliminate the pressure caused by thermal expansion and contraction.

Simple and fast machine rolling, easy and economical construction.

It is convenient to lay a thermal and acoustic layer.

There is no need for chemical caulking adhesives, which eliminates contamination and aging problems.

The roof does not require maintenance.

Can be produced on site.

Light weight, mostly made of lightweight materials, light weight.

Good durability and low maintenance.

High strength, stable structural performance, safe and reliable use.

It has good waterproof performance.

The appearance adaptability is strong, which can meet the appearance needs of different types of buildings.

Easy and fast installation. Factory-prefabricated or on-site assembly for quick installation.

It has excellent fire performance.

Metal roofing materials can be the best and are ideal green and environmentally friendly building materials.

(1) The overall structural waterproofing and drainage function, regardless of the shape of the building, can completely occlude the joints, and the whole roof has no nail holes, which can not only make the roof expand and contract freely when the temperature changes, avoid temperature stress, but also eliminate the hidden danger of water leakage caused by the system screw fixing method.

2) No need for chemical caulking adhesive, avoiding pollution and aging.

3) Mature integral roof opening and lightning protection system design.

4) Good air permeability, keep the overall structure naturally dry for a long time, and prolong the service life of the building.

5) Three-dimensional curved arc specific shape is easy to process.

6) The structure is simple, lightweight, safe, and can resist high and strong negative wind pressure, especially suitable in typhoon and heavy rain areas.

7) It is also suitable for the renovation of old roofs and the addition of new roofs to old roofs.

8) The construction is safe, simple, fast, accurate and economical.

Metal cambers are characterized by wear-resistant and durable.

Colored stone metal tiles, a bit expensive.
