Pass the Test of Typhoon "Capricorn"--- Let's Look at the Wind Resistance of BNBM Waterproof Roof Systems for Public Buildings

Recently, super typhoon "Capricorn" landed in Hainan, causing huge losses to local people's lives and property. Typhoon and extreme convection weather has been challenging the stability and safety of large public building roofing. After the typhoon, a large number of factory buildings collapsed, the roof was uncovered and damaged, many seemingly stable steel structure color steel tile roofs were also destroyed, the scene situation is shocking.

However, located on the eye action line of the typhoon center, the roofs of the two projects which were involved by BNBM Waterproof --- Hainan Boao International Innovative Pharmaceuticals Exchange and Conversion Center and the Danzhou City Sports Center "One and Two Pavilions", passed the "Capricorn" test and were stable as a rock in the storm, demonstrating a strong resistance to wind uncovering ability.

As the leading enterprise of polymer waterproof materials in China, OTAi brand of BNBM Waterproof is in the forefront of the national "technology flow" in single-ply roof waterproofing system. It has been deeply working in the field of metal enclosure system for many years. Due to the outstanding advantages of its products in durability, waterproof function, green and low-carbon, standardized construction, etc., it has significantly enhanced the stability of wind pressure resistance and waterproof capability of the roofing system.

Let's take a look at the technological code of wind resistance of BNBM OTAi's TPO single-ply roofing system

01 Non-Destructive Mechanical Fixing System

BNBM OTAi has more than 10 years of professional experience in the design and installation of TPO single-layer roof system. For the installation of TPO single-layer roof system, it is equipped with a special non-destructive mechanical fixing system, which is firmly combined with the roof structure through screws or anchoring parts to ensure that the TPO polymer waterproof material is closely connected with the roof structure to form a whole, even in the case of local damage. It can also ensure that the roof will not leak, but will not be lifted by the wind as a whole, greatly enhancing the ability of the roof to resist wind tearing.

02 Polymer Environmental Protection Materials

BNBM OTAi TPO single-layer roofing system uses thermoplastic polyolefin (TPO) waterproof membrane, which is not only lightweight, but also has extremely high strength and toughness, good environmental performance, strong safety, and anti-corrosion and heat insulation. Its installation has a complete set of advanced and mature application technology, under the action of strong winds, the elastic deformation ability of polymer materials can absorb and disperse wind, reducing the direct impact on the roof.

03 Experimental Testing of Wind Resistance

With its excellent design and performance, BNBM OTAi TPO single-ply roofing system has demonstrated strong defense power in the fight against Typhoon "Capricorn".  According to the analysis, the maximum wind force of this Typhoon Capricorn was 17, and the wind speed was about 63m/s. According to this wind speed, the negative wind pressure was about 3-4KPa, which was undoubtedly an extreme challenge to the roofing system. However, BNBM OTAi TPO single-layer roof waterproofing system easily crossed this difficult barrier with its advanced industry performance.

After the typhoon "Capricorn", through field visits, the roof of the Haikou project that our company participated in the construction was comprehensively tested and investigated. The roof of the building was intact without any deformation, water seepage and other problems, and successfully resisted the attack of the typhoon, which was highly recognized by the customer. BNBM Waterproof TPO single-ply roofing system has not only passed the test again and again by strength, but also has been favored and recognized by many large-scale projects, from aerospace, industrial plants to large venues, all over the country, and has been widely used and verified in a number of key projects at home and abroad.

As global warming intensifies, extreme weather such as "Capricorn" will become more frequent, and it is crucial to solve the problem of windproofing of building roofs. In the future, BNBM Waterproof will work with more partners, committed to technological innovation and product optimization, to quality masonry safe choice, to provide customers with more high-quality metal roofing solutions, to contribute to the development of the industry.
