Zero spangle Galvanized Steel Sheet in Coils Introductions
Hardness: soft (normal), hard, full hard
Zinc coating: 30-275 G /M², or on request
Zinc pattern: large zinc pattern, small zinc pattern, no zinc pattern
Surface finish: fingerprint resistant, chromate, oiled, unoiled
Zero Spangle Galvanized Steel : In hot dip galvanising, only a certain amount of aluminium is added to the zinc solution and no lead-free, antimony or tin is added to produce a non-bright product.
Influence of Plating Weight (Thickness) on Corrosion Resistance
The weight of the coating is the most important guarantee of corrosion resistance. The greater the thickness of the coating, the better the corrosion resistance, which has been proved by many accelerated tests and exposure tests. The thickness of the galvanised layer usually refers to the thickness of both sides, under normal circumstances, the commonly used galvanised layer on the market are double-sided equal thickness hot-dip galvanised.
Classification of zinc spangle
Large / Big zinc spangle (regular spangle): zinc spangle formed by free growth of zinc crystals in the normal solidification process after hot dip plating of steel plates in conditions where the zinc solution contains antimony or lead.
Minimum zinc spangle : because of the control of the growth of zinc flower crystallisation, so the surface grain structure is fine; because of the surface uniformity, so the surface quality after painting is excellent; paintability is better than conventional zinc flower.
No zinc spangle (zero zinc spangle): because the growth of zinc particles is completely controlled during the molten zinc fixing process, it is difficult to see zinc spangles with the naked eye; because the surface is uniform, the surface quality after painting is excellent.
Skin passed zinc spangle: the molten zinc is cured and then smoothed to obtain an extremely smooth surface; because the surface is smooth, the surface quality after painting is excellent.
Household Office Galvanised Sheet
Including air conditioners, washing machines, refrigerators, photocopiers, etc. Household galvanised sheet is mainly used for general forming applications and stamping.
| Application | Steel Grade | Standard | Function & Characteristics |
Stamping Steel | DX51D+Z, DX51D | GB/T 2518 | Including materials for general use, mechanical biting(LFQ Lock Forming quality), deep drawing, and ultra deep drawing. The coating and welding performance of alloying hot-dip galvanizing are superior. |
| Structural Steel | S250GD+Z, S250GD | GB/T 2518 | Structural steel is generally used for important purposes such as load-bearing, and is often used in steel structure projects, with good corrosion resistance and processing performance |
