Xi'an Huafeng Construction Engineering Co., Ltd. is a leading manufacturer and supplier of high-quality seam metal roof systems. With over 5 a long time of encounter, we offer inventive material arrangements that combine solidness, aesthetics, and vitality effectiveness. Our items are planned to meet the requesting needs of commercial, mechanical, and organization ventures, giving long-lasting security and esteem for your speculation.

Product Introduction

The roof system is a crucial component of any building, with strict design requirements. It must provide safety, durability, weather resistance, thermal insulation, sound insulation, aesthetic appeal, and easy maintenance. Our products excel in all these aspects, offering a comprehensive solution for modern construction needs.

Specifications

System Structure

• Standing seam roof panel: The thickness is usually 0.9mm-1.2 mm.
• Waterproof and breathable membrane: It is a high-density polyethylene non-woven fabric that blocks the invasion of wind and rain on the building structure. While strengthening the air tightness and water tightness of the building, it can also provide rare breathability, so that the water inside the enclosure structure can be quickly discharged, effectively avoiding the formation of mold and condensation water.

• Insulation and sound insulation layer: Rock wool is usually used, and its thickness needs to be determined according to calculation. It mainly plays the role of heat preservation and noise reduction, such as the noise after heavy rain and hail hit the surface layer.
• Vapor barrier: Generally, polyester film or high-density spunbond polyethylene film is used, and glass wool (with moisture-proof veneer) can also be selected. The vapor barrier can limit the water vapor inside the building from entering the roof, thereby minimizing the occurrence of condensation.

• Sound-absorbing cotton: Glass wool is usually used, and its bulk density and thickness need to be determined according to calculation.
• Dustproof layer: Generally, non-woven fabric is used, which is mainly used for dust and dust isolation, and is laid on the upper surface of the roof base plate.​​​​​​​

• Structural base plate: generally perforated galvanized or galvanized corrugated steel plate is used, the thickness is designed according to the purlin distance, and the perforation rate is calculated according to the project. It supports sound-absorbing cotton and thermal insulation cotton, and also plays a decorative role.
• Roof purlin: generally uses lining purlin and steel purlin, which play the role of structural support and slope adjustment

Features and Advantages

1、Anti-corrosion base material, strong durability
（1）Adopting grade AA3004 aluminum-magnesium-manganese alloy, it has strong anti-corrosion performance;
（2）Surface damage caused by transportation or construction does not affect its anti-corrosion performance;
（3）Certification by the British National Standards Bureau: The service life of this product in ordinary environment is not less than 40 years.
 
2、Reliable waterproof performance
（1）The fixing method adopts concealed buckle plus mechanical locking method, without any screws passing through the roof to avoid water leakage;
（2）The panel cross-sectional area is used to maximize drainage, with high drainage efficiency.
（3）The horizontal overlapped edges are hinged by a special hinge machine, which has good sealing and anti-capillary action measures.
（4）The sliding fixing seat is used to avoid panel damage due to temperature deformation.
（5）The use of mobile profiling equipment breaks through the restrictions on the length of the board under transportation conditions and reduces the longitudinal overlap of the board.
（6）Aluminum alloy roof panels and flashing boards are allowed to be welded, which perfectly handles the waterproofing problem of roof openings.

3、Good adaptability to shape
（1）The aluminum-magnesium-manganese alloy material used has both considerable strength and good flexibility, and is particularly suitable for roofs with complex shapes such as three-dimensional curved surfaces;
（2）The unique production technology of fan plates, curved plates and fan curved plates can perfectly realize various design shapes while ensuring waterproof capabilities.

 4、Beautiful materials and easy to use
（1）The original color panel has a very strong metallic luster;
（2）PE or PVDF coating can be applied externally to meet the color requirements of design and use;
（3）Generally, no washing and maintenance are required during use.

5、On-site press production method
High flexibility, easy to adjust production parameters according to the construction site conditions, conducive to shortening the production cycle and ensuring product quality
