Business Mirror reported that as the leading manufacturer of GI sheets for roofing in the Philippines, Puyat Steel has welcomed the new standards for galvanized steel coils and sheets set by DTI Bureau of Philippine Standards, which recognizes the need for disaster resilient housing, and the protection of the consumer who may be uninformed of the standards of roofing products available in the market.
The Department of Trade and Industry publicly released last December 2020, the guidelines for DTI Departmen Administrative Order 2010, which sets mandatory product standards and requires testing and certification of galvanized steel coils and sheets for roofing materials. DAO 20-10 sets the minimum total thickness for steel coils and sheets intended for roofing at 0.4mm, which can withstand more strong winds of 200kph and up. With the use of thicker steel sheets and the proper fastening to the roofing frames, roofs and houses will be more resilient during disasters. The minimum thickness of 0.4mm is more in line with the need for stronger construction and roofing materials.
Due to its geographical location, the Philippines is constantly battered by tropical cyclones, with approximately 20-25 tropical cyclones entering the Philippine area of responsibility yearly. With this circumstance, it is crucial to ensure the integrity and strength of construction materials in the country to withstand frequent storms.”
