Quality control: use a caliper to verify the thickness of the CGI sheet. Depends on thickness of the zinc coating. Example: if the roof slope measures 2.32 m, then the length of the CGI sheet should be 2.37 m (2.32 + 0.05 m). The budget price includes many other factors, incoterms, and internal cost adjustment. Suggested materials to accompany the CGI sheets: Some specifications may vary from national standards and local market conditions. Weight calculator for sheet metal.

Premium Galvalume Sheets for Solar Structures. 20µm/side à 275 g/m2 à Z275 (ASTM A653 or EN 10346), A minimum of 20µm on each side is recommended à 137.5 g/m2 on each side, Quality control: Use a coating thickness gauge to verify the thickness of the zinc coating. The most common way to measure GSM is using a scale and a ruler, but there are sometimes other methods needed for industrial processes. How many candles are on a Hanukkah menorah? Budget price Sheets ordered by gauge weight or thickness are subject to standard thickness and weight tolerances. In exceptional circumstances such as major difficulties of accessibility (mountainous and remote areas), it is possible to use exceptional solutions, choose thinner CGI sheets to reduce the weight of the transportation, if CGI sheets have to be carried by humans or animals. The zinc coating thickness can be verified using a coating thickness gauge or magnetometer (EMEAMEASGC01), which measures the thickness of the zinc coating applied to the CGI sheet. The galvanization method used must be hot-dip galvanization as it better ensures the durability of the CGI sheets. In this page you can calculate sheet metal weights without depending on any standard measure. When positioning the roofing nails, you need to place more roofing nails all around the edges of the roof: at eaves overhang, ridge, verges and hip angles (areas submitted to increased wind pressure). (Example: 16 x 1.10 = 17.6 à 18 CGI sheets to be ordered for the entire roof). Galvanized steel is regular steel sheets that have been coated in zinc to make them corrosion resistant.Regular steel is made of iron which will rust when exposed to moisture, either in the form of rain or ambient humidity. Electrogalvanized conforms to ASTM A591 You can detail your project with multiple calculations. Assemble the CGI sheets on wooden frames with roofing nails (see item EHDWNAILRS01). Other metal and alloys such as aluminium-zinc and aluminium can also be used to protect the steel sheet from corrosion. 0.4 mm (30 gauge) can be used for shelters when the wind speed is lower than 200 km/h, the distance between laths/battens/purlins is 0.60 m maximum and the area is not prone to snow. Thickness is an important factor for strength and durability. In such cases it is highly recommended to seek the advice of a shelter expert. Below is the conversion for galvanized steel sheet (including CGI sheet, ridge cap and fascia cap). in india? Shear Connectors / Ribs are optional. It is possible to increase the zinc coating thickness in order to increase the service life (durability) of the CGI sheets. Grade: It is possible to use a structural steel (low quality such as S220GD), but it is not recommended as it is usually more expensive than mild steel for cold forming. A 20 µm coat of zinc should be applied per side of the CGI sheet (total of 40µm for both sides of the CGI sheet equivalent to 275g/m²). National Steel Processor - Offering GI Steel Sheets, Thickness 1-2 mm at Rs 45.5/kilogram in Ahmedabad, Gujarat. The GI decking sheet is attached to the concrete by method for mouldings on the sheet which prevent the cement from slipping on a level plane and disconnecting vertically. Usage areas of sheet … In a marine environment (within 1 km of the coast), CGI sheets can be painted with zinc-rich paint to increase service life. What does contingent mean in real estate? Depends on the wind, the roof pitch, and if the length of the roof slope takes one or several CGI sheets (see the tables below).

(Example: 16 x 1.10 = 17.6 à 18 CGI sheets to be ordered for the entire roof) Usage: When purchasing CGI sheets to repair existing roofs, it is important to ensure that the pattern of corrugations is compatible, otherwise leakage may appear. The values mentioned in the table below are approximate. The Galvanized Sheet Gauge is based on the U.S. Standard Gauge. These sheets and plates are available in different dimensions and material to … : use a caliper to verify the thickness of the CGI sheet. Allowable loads are applicable for sheets spanning over a minimum of four supports and for permanent shuttering only. Find the address and contact details for all our branches. ... for calculating per SQM wt of GI sheet just multiply 7850 by thickness in mm i.e per SQM wt of 0.55 mm sheet 7850x0.55 = 4.31 Kg/sqm. Typical Mechanical Properties of Parmatech PIM Alloys. They were calculated for a shelter with a 15-30° gable roof pitch built in a rural area with low vegetation, using a 38mm thick lath/batten/purlin. Total quantity of CGI sheets to order must include the overlapping of each sheet with the next one which can be 5 to 26% of the surface to cover: Percentage of overlapping if one CGI sheet for the entire roof slope: Percentage of overlapping if several CGI sheets for the entire roof slope: To have a good approximation of the quantity of CGI sheets needed to cover a gable roof (pitch = 20°, wind speed > 150 km/h), you need to: Formula to determine the number of CGI sheets needed to cover the roof slope, N = S / (surface of CGI sheet x (1 - % overlapping)), surface of CGI sheet = total width x length of CGI sheet, % overlapping = percentage indicated in table above, It is recommended to include a 10% loss to ensure that you will have enough CGI sheets to cover the roof. 1.- Product Details Name - GI Roffing Sheet, GI corrugated sheet, GI sheet, Hot dipped galvanzied steel roofing sheet, HDP GI corrugated sheet, Aluzinc coated roofing sheet, Galvalume steel corrugated sheet, Galvalume aluzinc steel coil,GL sheet, GL roofing sheet,PPGI roofing sheet, PPGI corrugated sheet. Why don't libraries smell like bookstores? It is also important to know the weight for machining metal sheets no matter the material. In this case, the roof frame must be modified à the spacing of the CGI sheet support (lath/batten/purlin) must be reduced to keep its strength. density of gi sheet are distributed into various kinds on the basis of their shapes, sizes and dimensions. When did organ music become associated with baseball? Galvanised Corrugated Sheet & Profile \ Applications & Grades. For a more accurate quantity of CGI sheets and quantity of fasteners/fixings needed to securely attach the CGI sheets to the roof, it is highly recommended to use the Roof Estimate Form (Excel spreadsheet) provided with the CGI sheet roof covering manual (link to be included). total width with 31in. The equivalent thicknesses differ for each gauge size standard, which were developed based on the weight of the sheet for a given material. Density Table. Contact US. Most common from 6 – 20ft (1.83 – 6.00 m), as per contract. Galvanized is a term long used to describe steel sheets coated with zinc. Sheets can be subjected to bending and forming without the flaking of zinc. ft. heavier or .0037 inch thicker than the weight or thickness of the corresponding U.S. Standard Gauge Number, regardless of coating weights. A density table is a table that displays the density of a substance in the form of a table. This coating can be exceptionally lowered to 240g/m² when higher grade is not available. Place the CGI sheets on a wooden pallet and ensure that there is a slight slope. WEIGHT PER Pc. - search is the most efficient way to navigate the Engineering ToolBox!
