DX51D Galvalume Steel Strip for Building Panels and Roofing
DX51D Galvalume Steel Strip for Building Panels and Roofing
Feature
-
The DX51D Galvalume Steel Strip is a corrosion-resistant Galvalume Metal strip with a silvery-white aluminum-zinc alloy surface, made for building panels, automotive parts, household appliances and farm structures. It paints without pretreatment, takes welding and forming well, and comes in 0.16mm–2.5mm thicknesses with alu-zinc coatings from 30 to 150gsm.
The Galvalume Metal strip starts with an alloy that does two jobs at once. The zinc side gives sacrificial protection, the aluminum side supplies a barrier layer, and together they deliver corrosion resistance roughly 3 times that of a pure galvanized strip — with coating performance that can outlast hot-dip galvanized steel strip by 2 to 6 times. The surface shows a neat zinc flower pattern, which is why it gets used as exterior panels on buildings, and the adhesion with paint is strong enough that coating can go straight on without pretreatment and weathering treatment.
From the shop floor side, the strip behaves itself: formable, weldable and paintable, with a standards list — AISI, ASTM, BS, DIN, GB, JIS, plus JIS3321/ASTM A792M — that keeps it simple to slot into existing drawings. ZZ Group backs the material with direct supply of finished products, import customs clearance acted on your behalf.

| Surface Treatment | Feature |
| Chemical Treatment | minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
| retain the bright metallic luster for a long period | |
| Oil | minimize the tendency for humid-storage stain |
| Chemical Treatment and Oil | The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations. |
| Dry | must be transported and stored with special precautions to preserve low-humidity conditions. |
| Anti-finger print | minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
● Alloy make-up: composed of 55% aluminum, 43.5% zinc and 1.5% Silicon, which is what gives the strip its corrosion backbone.
● Paint-friendly: excellent adhesion with paint, so coating goes on without pretreatment and weathering treatment.
● Corrosion edge: resistance about 3 times that of pure galvanized strip, driven by the zinc's sacrificial protection and the aluminum's barrier protection.
● Coat-life: coating performance out-performs hot-dip galvanized steel strip by 2-6 times.
● Decorative surface: beautiful zinc flowers on the surface, suitable for exterior panels of buildings.
● Workable: formable, weldable and paintable, which keeps downstream lines moving without surprises.
● Coating spread: alu-zinc coating 30-150gsm; spangle in regular, small or big.
Judged on the product alone, the reasons stack up cleanly:
● A coating that beats pure galvanized strip by about 3 times on corrosion resistance, and hot-dip galvanized coating by 2-6 times on performance.
● A silvery-white surface with real zinc flowers — decorative enough for exterior panels, tough enough for industrial duty.
● Paint that goes straight on with no pretreatment and no weathering treatment, which shortens finishing lines.
● An alloy system of 55% aluminum, 43.4% zinc and 1.6% silicon, from the same family trusted in daily use across building, automotive, appliance and agricultural products.
● One supplier for the whole deal: direct supply of finished products, import customs clearance acted on your behalf, and a reputation built on years of Philippine market experience.
That's the short version of why Galvalume Steel buyers keep coming back with the same spec. The DX51D Galvalume Steel Strip is a workhorse material sold by a group that treats the strip as just one part of a clean delivery. When the quote lands, you get the alloy, the coating, and the shipping all handled in the same conversation.
The Galvalume Metal strip shows up across more end products than most buyers expect. The main use groups:
● Buildings: roofs, walls, garages, soundproof walls, pipes and modular houses, etc.
● Automobile: muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc.
● Household appliances: refrigerator backboard, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc.
● Agricultural use: pig house, chicken house, granary, greenhouse pipe, etc.
● Others: heat insulation cover, heat exchanger, dryer, water heater, etc.
Every order travels under standard sea-worthy packing, which is what the specification calls for and what port logistics expect. ZZ Group can supply finished products directly, so a Strip Gl order leaves the source and heads your way without extra hand-offs. For buyers who want the whole thing handled, the team can act for import customs clearance as part of the same transaction, and that matters on tight delivery calendars.
Q: Which standards can this Galvalume Steel Strip be made to?
A: The list covers AISI, ASTM, BS, DIN, GB and JIS, with JIS3321/ASTM A792M also stated in the spec. Grade is DX51d, and other grades are all according to the customer's request.
Q: What thickness and width can I order?
A: Thickness runs 0.16mm-2.5mm, all available; width and length are according to your requirement. Pass the numbers over and the mill works to them.
Q: What does Az50 Galvalume coating mean in practice?
A: The alu-zinc coating ranges 30-150gsm, and the alloy structure — 55% aluminum, 43.4% zinc and 1.6% silicon, set at 600℃ — is what delivers the corrosion resistance and paint-friendliness this strip is known for.
Q: Where does Strip Gl sit in the product family?
A: Strip Gl is the short form the trade uses for the galvalume-coated strip family — the same Galvalume Steel Strip covered on this page, offered in DX51d and other grades on request.
Q: How do surface treatment choices change the strip?
A: Pick from Chemical treatment, oil, dry, Chemical treatment and oil, or anti-finger print. Each one has a different effect on humid-storage staining, so the right pick depends on your climate and handling.
