Corrosion resistance
Zinc acts as sacrificial anode, protecting steel in harsh environments
HOT DIP GALVANIZING SERVICES IN THE PHILIPPINES
Industry-grade zinc coating for structural steel, angle bars, beams, and fabricated assemblies. Protecting your steel against corrosion — from Metro Manila to nationwide project sites.
ABOUT OUR GALVANIZING SERVICE
Hot dip galvanizing services in the Philippines are essential for structural steel exposed to outdoor, industrial, or coastal environments. At Regan Industrial Sales Inc., our galvanizing process bonds a protective zinc coating to the steel surface, creating a metallurgical barrier that prevents rust, oxidation, and atmospheric corrosion.
Our Quezon City facility operates a fully controlled pre-treatment line — from chemical cleaning and pickling to fluxing — ensuring the zinc adheres uniformly to every surface. The result is a consistent coating that complies with international standards and extends the operational life of your structural components.
ASTM A123 compliant
Coating thickness meets international structural galvanizing standards
Wide product range
Beams, angle bars, perforated plates, fabricated assemblies
Fast turnaround
Efficient production line with prompt delivery to job sites
HOW GALVANIZING WORKS
STEP 01SURFACE PREPARATION & PRE-TREATMENT
Before the galvanizing bath, components are quenched in water or air- cooled to solidify the coating and lock it to the substrate. Each batch is visually inspected for bare spots, drips, or uneven coverage.
- Degreasing agent
- Alkaline solution bath
- Pickling solution
- Hydrochloric acid (HCl)
- Flux solution
- Zinc ammonium chloride
- Pre-treatment stages
- 3 (degrease → pickle → flux)
STEP 02ZINC BATH IMMERSION
Prepared steel components are immersed in a bath of molten zinc at approximately 450°C (850°F). At this temperature, zinc and steel form a series of zinc-iron alloy layers through a metallurgical reaction.
- Bath temperature
- 449-452°C
- Zinc purity
- ≥98.5% Zn
- Standard
- ASTM A123 / ISO 1461
- Min. coating thickness
- 45-85 μm (grade dependent)
STEP 03QUENCHING, INSPECTION & FINISHING
After the zinc bath, components are quenched in water or air-cooled to solidify the coating and lock it to the substrate. Each batch is visually inspected for quality assurance.
- Quenching method
- Water quench or air cool
- Thickness test
- Magnetic gauge per ASTM A123
- Visual inspection
- 100% per batch

Frequently asked questions
What is galvanizing?
Galvanizing is the process of applying a protective zinc coating to steel or iron to help prevent rust and corrosion. It is commonly used for structural steel, fabricated components, poles, brackets, frames, and other products exposed to outdoor or industrial conditions.
What steel products can be galvanized?
Galvanizing may be suitable for structural steel sections, pipes, plates, fabricated assemblies, railings, frames, poles, brackets, and other steel components. Suitability depends on the material, dimensions, design, surface condition, and fabrication details.
How long does galvanized steel last?
The service life of galvanized steel depends on the coating thickness, environment, exposure to moisture, chemicals, and maintenance conditions. In many outdoor and industrial applications, galvanizing can provide long-term corrosion protection.
Can fabricated steel be galvanized after welding?
Yes, fabricated steel can often be galvanized after welding. However, the design should allow proper drainage and ventilation during the galvanizing process. Weld quality, enclosed spaces, overlapping surfaces, and material compatibility should also be reviewed before processing.
What information should I provide when requesting a galvanizing quote?
Provide the steel type, item dimensions, quantity, total weight, fabrication drawings, surface condition, delivery location, and required schedule. Photos or technical drawings can help the team assess handling, preparation, and processing requirements.
