As the leading manufacturer of GI sheet for roofs in the Philippines, Puyat Steel welcomes the new standards for galvanized steel coils and sheets set by the DTI Bureau of Philippine Standards under Administrative Ordinance DAO 20-10. The Filipino steelmaking pioneer supports the mandate of DAO 20-10 as it recognizes the need for disaster-resistant housing and the protection of the consumer who may not be aware of the roofing product standards available in the market.
The Ministry of Trade and Industry published the guidelines for the DTI Department of Administrative Ordinance (DAO) 2010 in December 2020, which sets binding product standards and requires testing and certification of galvanized steel coils and sheets for roofing materials
What does this mean for the Filipino consumer? DTI Secretary Ramon M. Lopez stated: “This new technical regulation will ultimately ensure the safety and protection of consumers, which is also a top priority for DTI.” DTI Consumer Protection Group (DTI-CPG) Undersecretary Atty. Ruth B. Castelo underlined the need for a regulatory scheme for galvanized coils and sheets. “Due to its geographical location, the Philippines are constantly hit by tropical cyclones, with around 20 to 25 tropical cyclones coming into the Philippines’ area of responsibility each year. In these circumstances, ensuring the integrity and strength of building materials in the country to withstand frequent storms is critical. “
DAO 20-10 specifies the minimum total thickness for steel coils and sheets for roofs at 0.4 mm, which can withstand stronger winds from 200 km / h. By using thicker steel sheets and correctly fastening them to the roof frame, roofs and houses become more resilient in the event of disasters. The minimum thickness of 0.4 mm is more in line with the need for stronger construction and roofing materials. In the 2017 National Housing Authority’s Design Manual, the minimum standard thickness for roofing membranes was set at 0.55 mm, according to their “Parameters for Resistance to Disaster of Residential Buildings”, particularly with regard to Typhoon Yolanda in 2013. While the standard of DAO 20-10 Da the minimum thickness of 0.4mm is less than the 0.55mm specified by NHA, it is more acceptable than much thinner sheets still available in the market, also taking into account affordability or cost to end-users / low-income families were. DTI’s DAO 20-10 enforces the need to use stronger building materials for roofs as this offers both environmental and economic realities for the Filipino consumer.
DAO 20-10 was published in December 2020 following a series of public consultations conducted by the Bureau of Philippine Standards (BPS-DTI) in 2019. This is in line with the mandate of the BPS-DTI to act as the National Standardization Body (NSB) of the Philippines and develop and implement standards for all products in the Philippines to protect the consumer.
A group within the steel products industry rejects DAO 20-10, arguing that these minimum standards would make the cost of a roof more expensive for regular homeowners. However, the cost of using higher standard roofing sheeting, as per the NHA Housing Design Manual guidelines for low cost housing, only adds 1% to the total cost of housing, as roofing sheeting is only 3% to 5% of the total cost of the house. DAO 20-10 aims to protect consumers who are not so familiar with technical product standards by enforcing minimum standard thicknesses and strengths for roofing membranes available on the market. Puyat Steel Corporation fully supports and ensures compliance with the DAO 20-10 through its products as it recognizes the need for the government to implement the measures required for stronger roofing materials to protect the end user from the challenges of climate change.
