We are leading supplier of Zinc-Coated Galvanized Sheets. The coating thickness of GALVALUME sheet roofing is AZ 150 GSM, whereas Galvanized steel sheets are usually having only 120 GSM/m2 coating of Zinc. The continuous hot-dip galvanizing process offers a wide protection range from Z100 to Z600 in addition to a tight bond between the coating and the steel. thickness (Figure 2) of each zinc coating varies. BLD Steels Private Limited - Offering GALVANISED zinc colour 120 GSM GI Sheets, Thickness Of Sheet: 0.25 - 3mm, 250-550mpa at Rs 50/kilogram in New Delhi, Delhi. Zinc coating: 120 gsm (min) Thickness: 0.40 mm (min) for FS type Steel : 0.50 mm (min) for structural steel Substrate: ASTM A653 FS Type A or structural grade Paint system: Molawan Special requirement: Top and bottom coats are the same color Zinc coating (Z) produced on both sides by hot-dip galvanizing extends the service life of the end product by protecting the steel from corrosion. Zinc entrapment, poor drainage, and enormous horizontal surfaces will lead to higher zinc … What these numbers conceal is that hot dip galvanizing produces a coating which is bonded metallurgically to the steel. GALVALUME roofing is highly corrosion resistant, and transmits heat at a rate of only 65 watt/m2 as compared to Galvanized steel, which transmits at a rate of 120 … Coating Mass (g/m 2) = Coating Thickness (µm) x 7.05. It’s commonly used to describe paper - typical photocopier paper is 80 gsm. The mandatory Minimum zinc coating as per SASO ASTM A653M-A1-15 is 60 gsm (grams per square meter) in order to deliver the minimum expected product performance and life span. In addition to steel thickness, the … Read about company. In general, the thicker the steel, the thicker the zinc coating obtained and the longer the lifespan of your protection. 120 Gsm Gi Zinc Coated Metal Roofing Steel Galvanized Corrugated Sheets , Find Complete Details about 120 Gsm Gi Zinc Coated Metal Roofing Steel Galvanized Corrugated Sheets,Galvanized Corrugated Sheets,Steel Roofing,Roofing Steel Sheets from Steel Sheets Supplier or … ‘gsm’ means grams per square metre. Features: Water Proof Coating Thickness (µm) = Coating Mass (g/m 2) x 0.14 **Actual zinc pickup after galvanizing will rely on the average thickness of coating and section design. Recommended Specifications. 120 gsm paper is a luxury type, quite thick. A The coating designation is the term by which the minimum triple spot, total both sides coating weight [mass] is specified. it should be with primer coat of epoxy primer of 5-7 microns thick, finish painted with polyester paint of 12-16 microns thick and back coated with alkyd backer of 5 … Material with high tensile strength and Uniform Zinc Coating of 120 GSM. Applications that are closer to the sea, offshore, or in urban areas will require a heavier zinc coating. Get contact details and address | ID: 19942725862 Galvanised Coil: Specifications: Galvanised as per IS 277 or equivalent grades like ASTM A 653, EN10327 Thickness (mm): 0.10 to 1.6 mm ( Galvanized) This practical aid examines the following zinc coatings: batch hot-dip galvanizing, continuous sheet galvanizing, zinc painting, zinc spray metallizing, mechanical plating, electrogalvanizing, and zinc plating; to help architects, … Cold rolled steel coil made up of base steel as per IS 513 grade “D” quality, galvanized as per is 277 with zinc coating of 120 grams/sq.mtr.
