What are the products manufactured by the Philsteel group of companies?

The Philsteel Group of companies is behind supremely global and proudly local brands including GALVALUME® 55, COLORBOND and GALVABOND.

In 1981, Philsteel notched a milestone in the Philippine construction industry with the introduction of GALVABOND, which offers world-class lock-forming quality, excellent coating adhesion, superior corrosion resistance, weldability and formability.

In 1999, Philsteel pioneered the introduction of roofing technologies in the Philippines using patented, cutting edge technologies, becoming a trailblazer when it introduced GALVALUME® 55, the first locally produced 55% AL/ZN coated steel sheet that provides superior roofing protection for Filipinos.

Under the helm of Philsteel Holdings Corporation, Steel Corporation of the Philippines manufactures GALVALUME® 55and GALVABOND PURE ZINC in its continuous galvanizing plant located in Balayan, Batangas.

COLORBOND was among the first pre-painted metal roofing products in the Philippines. With the breakthrough success of GALVALUME® 55, Philsteel began using 100% genuine GALVALUME® 55as substrate for all Colorbond pre-painted roof profiles in 1999.

These core products were utilized to expand into a variety of roofing profiles that the Philsteel Group of companies currently offers. COLORBOND with various roof profiles are manufactured in rollforming plants located in Bulacan; Carmona, Cavite and regional plants located nationwide.

What are the advantages of using metal/steel roofing materials compared to others?

Metal roofing is sustainable and better for the environment because steel is fully recyclable. It is also easier to clean and has a longer lifespan than other materials that offer the same aesthetics. As a roofing material, metal can also carry more color options than other types of roofing materials. Because it is factory-painted, it serves a longer life than manually-painted materials.

Why is GALVALUME sheet called by other names? Are all of these products the same?

Galvalume is a 55% aluminum, 43.5 aluminum, 1.5% silicon coated sheet steel developed by Bethlehem Steel and sold commercially under the trademark GALVALUME, starting in June 1972. Bethlehem Steel later licensed other major steel companies to produce and sell the product using its patents and technology.

In the Philippines, Philsteel Holdings Corporation, through its subsidiary Steel Corporation of the Philippines, holds the trademarked copyright for the brand name GALVALUME® 55.

Philsteel became a trailblazer when it introduced GALVALUME® 55, the first 55% aluminum and zinc alloy coated steel sheet that provides superior roofing protection for Filipinos. GALVALUME® 55 roofing sheet conforms to the requirements of the Philippine National Standard for Roofing (PNS 67: 2014) for 55% AL/ZN alloy-coated steel sheet, offering peace of mind against the onslaught of extreme heat and heavy rainfall. Steel Corporation of the Philippines prints the actual Total Coated Thickness on the sheet allowing the consumer to know exactly the thickness of the roofing sheet they are buying. Unlike GI sheets with only zinc coating, GALVALUME® 55 coating is composed of 55% Aluminum, 43.5% Zinc and 1.5% Silicon. This composition provides superior roofing protection including:

  • Superior rust protection Galvalume® 55 roofing sheet provides 3 to 6x longer protection against rust compared to ordinary GI giving the customer a longer service life for his roof.

  • High heat reflectivityGalvalume® 55 roofing sheet has superior reflectance of the sun’s heat, allowing a cooler environment inside the house, greatly reducing the cost of electricity.

  • Retains original silvery finish for a longer periodGALVALUME® 55roofing sheet retains its shine and silvery finish making your roof look new for a longer period of time.

Why is GALVALUME an excellent material for roofing?

Ideal for modern day steel roof designs which are strong, yet lightweight, GALVALUME sheet roofs won’t crack and peel when subjected to the sun and weather unlike conventional nonmetallic roof systems.

GALVALUME sheet is an ideal material for roofing because of its extraordinary outdoor corrosion resistance that results in longer product usage. The product can readily be rollformed into a variety of profiles, as well as formed and stamped into tile and shingle facsimiles. It is also factor- painted to impart color and extend durability.

In the Philippines, Philsteel Holdings Corporation, through its subsidiary Steel Corporation of the Philippines, holds the trademarked copyright for the brand name GALVALUME® 55.

How does the corrosion resistance of GALVALUME sheet compare with that of galvanized sheet, and how long can a GALVALUME sheet roof be expected to last?

GALVALUME sheet has been successfully used in roofing applications for more than 40 years; it has been evaluated in outdoor R&D tests for well over 50 years worldwide. Based on these tests, in which corrosion weight losses were measured and compared with galvanized sheets, GALVALUME sheet is projected to outlast galvanized sheet (with an equivalent coating thickness) in various atmospheres by up to nine times. Likewise, recent inspections of 8-degree low slope GALVALUME roofs up to 35 years old in the eastern U.S. confirm the R&D results. These roofs are in excellent condition and are projected to last 50 to 60 years before requiring major maintenance.

In the Philippines, Philsteel Holdings Corporation, through its subsidiary Steel Corporation of the Philippines, holds the trademarked copyright for the brand name GALVALUME® 55.

What is the heat and sunlight reflectivity of GALVALUME roofing products?

GALVALUME offers good heat and sunlight reflectivity because of its bright, white reflective surface as a result of the presence of 55% aluminum in its coating. During summer months, it makes buildings cooler by efficiently reflecting away sunlight and reducing the amount of heat transmitted into the building. R&D testing in temperate countries also shows that the use of GALVALUME makes buildings warmer in the winter by reflecting inside heat from the underside of the roof back into the building.

Tests have also shown that only half as much heat from solar radiation is transmitted into a building fitted with a GALVALUME roof compared to a galvanized roof, and almost one-third less heat compared to a terra-cotta roof. This level of thermal reflectivity means that a GALVALUME roof can reduce cooling costs during hot weather and heating costs during cold weather, giving energy savings to the end-user.

In the Philippines, Philsteel Holdings Corporation, through its subsidiary Steel Corporation of the Philippines, holds the trademarked copyright for the brand name GALVALUME® 55.

What types of insulation are recommended for GALVALUME® 55 roofs? Are there any to be avoided?

By far, fiberglass roll insulation is the most commonly used insulation for GALVALUME steel roofs on nonresidential buildings. It can be used in any of the available thicknesses to give the required insulation value. One of the main benefits of retrofitted GALVALUME roofs installed over leaking nonmetallic flat roofs is the ability to add insulation under the new GALVALUME roof and realize significant energy savings from reduced heating and cooling requirements. In such instances, fiberglass roll insulation can either be placed on top of the old nonmetallic roof or under the new retrofit roof.

Wet insulation, which may be rain soaked at the site or wet from condensation or a leak in the roof, should not be in contact with GALVALUME roof panels. Insulation should be dry when installed and kept dry after installation. Fiberglass insulation retains water and can cause rapid inside-out corrosion on GALVALUME sheet panels. Also, spray-on insulation is sometimes used inside buildings under roofs and on siding. This insulation may contain fire retardant chemicals that can be corrosive to GALVALUME sheet. Manufacturers should be consulted about such fire retardant additives if spray-on insulation is used.

  • Processed under strict quality control to assure lifetime performance, durability and flexibility.

What makes COLORBOND different from other pre-painted roofing materials?

Philsteel’s COLORBOND is a superior pre-painted GALVALUME® 55 steel strip. It is produced through a continuous color-coating process under strict quality control to ensure a complete metal to paint bond.

COLORBOND pre-painted roof profiles are factory-painted roofing materials that are made using 100% genuine GALVALUME® 55 as a substrate. Roof durability is reinforced with the dual layers of paint (finished and primer) top and bottom coats that provide additional corrosion protection and longer lasting color and shine.

Why is METAL CLADDING superior over conventional cladding?

Conventional cladding used wood and cement boards to provide fascia ceiling and sidings needs. Metal cladding is a better option that offers pest-free, rust-free and fire-resistant fascia, ceiling and siding. Metal cladding provides beauty and durability that lasts years of usage. Metal is also the most sensible and economical alternative to wood, concrete, gypsum and mineral fiber boards.

The companies under Philsteel Holdings — Philmetal and Premier Shelter – offer this global class metal cladding under the trademarks of Versa Clad, EZ Clad and Panel Rib.

What is STEELDEK and what is it used for?

Steeldek is a structural metal decking profile used to support concrete flooring and recommended for high-rise buildings and infrastructural bridge decking.

The advantage of using Steeldek is the significant 30% savings on concrete, rebars, time and manpower during installation. Also, cement pouring can be done without any propping support so that people and moving traffic can still continue their work underneath.
