Exposing to extreme weather for a long time, choosing poor roofing materials, wrong installation techniques… are the main reasons causing the roof damage.
For the pre-engineered steel buildings and factories, the rusty or leaky roof causing businesses a lot of damage, affecting the production process, the productivity as well as the quality of stored goods. Moreover, it takes more money and time to get the factory roof repaired.
Therefore, from the view of well-established enterprises or experienced contractors, the investors need to consider the anti-leak roofing solutions from the project planning phase.
◆ Choosing an experienced builder
This is one of the top leak prevention solutions. “If the roofing is not done properly, it will definitely leak after a short time of use” – a representative of a reputable construction contractor commented. He also noted, during the roofing process, attention should be paid to the appropriate roof slope, to avoid stagnant water, causing rust and leakage. Besides, it is necessary to do the roofing properly so that the roof does not blow away in high winds, and use sealant in the right places such as the screw head and the bottom of the roof.
In order to limit seepage and leakage, regular roof maintenance should be carried out. Enterprises should periodically check the roof after the factory is put into operation for a few years. This helps detect leaks early and can fix them in time. The roofs can last without leaking for about 50 years with proper and good periodic maintenance.
If the construction unit does not give any advice, the enterprise can inquire about the period of periodic inspection. During the inspection, look for rust, missing screws, cracks and holes in the roof. For corrugated steel roofs with low rust, it is necessary to clean the rust before painting with anti-rust paint. Add screws in the missing places and replace the corroded screws. For corrugated steel sheets that have been seriously corroded, it is best to replace them with new ones. It is also recommended to repair or consider replacing the damaged roof of the factory.
◆ Choosing qualified materials and solutions from the very beginning
This is the simplest method to reduce the risk of leaks. High quality coated steel is always more durable than conventional coated steel. Today, some types are also integrated with anti-rust technology thanks to the coating layer, helping to better protect the corrugated steel roof.
01/ The rib design
The rib height is up to 75mm, meeting even a 2% roof slope design. As a result, investors can make the most of the allowed construction area for the project.
The 360° seaming technology improves the water tightness performance: seal as a can. Panel length can be tailored following the availability of on-site roll forming service which minimizes the need for lengthward overlapping and reduces installation cost.
When the temperature changes, the movable seam belt with seam hook allows the roof system to expand independently of the underlying frame, allowing the entire roof system to slide 100%, preventing deformation and leakage.
02/ Reduces wind upliff risk with wind upliff test
Certified by FM Approvals (U.S) for safety and quality, the new generation LYSAGHT® SMARTSEAM™ meets the strict requirements of investors.
The high rib and transverse flute reduce windnoise, wind uplift and improve anti-deformation performance.
03/ Sustainable materials
Using COLORBOND® & ZINCALUME® with the breakthrough innovation in ACTIVATE™ technology with the unique composition and microstructure of 4 phases for superior corrosion resistance, the new generation LYSAGHT® SMARTSEAM™ protects the factory in the harshest environmental conditions.
04/ Consulting service at the construction site
NS BlueScope Lysaght provides technical support services at the construction site, including offline training to the construction team on proper storage of construction materials, correct installation technique, and construction safety, in order to maximize the effectiveness of the LYSAGHT® SMARTSEAM™ solution, guaranteeing the investor the quality of the work.
Some factories in Vietnam have chosen the new generation LYSAGHT® SMARTSEAM™ for optimal anti-leakage performance.
