These include labour, consumables, tools, tackles and overheads. A variety of tools are used to cut raw material. The following are the various scraps that are maintained. Special band saws for cutting metal have hardened blades and feed mechanisms for even cutting. Usually, the sheet metal fabrication cost ranges from $754 to $1,624 for materials and labor, at an average of $1,189. Per Square Feet Rs.180/-. Typical Rates for Fabrication, Erection and Testing of Pipelines for Costing with Example. Non-conforming material that cannot be reworked or used and has no value except for its material content. Typical rates for various piping materials are enclosed for reference. Operation Scrap. Assembly Scrap 2. For instance, 6 mm round, cold drawn grade 304 steel with 15% reduction in area will have an ultimate strength of about 800 MPa. a) Mild steel (MS), B and C class piping: Rs. Having uniform shapes and sizes of raw materials reduces the amount of metal fabrication necessary to create a product and dramatically decreases production times. With the increase in size of a material, cold working necessary to achieve high tensile properties will not be suitable, owing to the rapid work hardening rate of large surface sections. 90/- per inch dia per metre length. The result is a lower cost per piece fabricated. Fabrication is the process of constructing products by combining diverse, typically standardized parts. Percentage scrap that occurs during production of the material if the material is an assembly. b) SS 304 piping ( Sch 5): Rs. The fact that different suppliers are required by the … The usefulness of standardized raw materials for the numerous metal fabrication processes is immediately apparent. Material Used: 61.5mmx45.5mmx1.2mm thickness aluminium Section for outer Frame.40mmx1.8mmx1.2mm thickness aluminium Section for window Shutters 4mm Plain Glass, TPI wheel TVS or EPDM gasket, Star lock, weather Proof Silicon Sealant. The aluminium fabrication rates in Bangalore for windows are given below. pipelines iii. Fabrication and manufacturing are two mechanical processes involved in the production of merchandise. A small project using sheet metal costs as little as $300, while a large project costs as much as $2,500. marko buliæ technical calculation and estimator's man-hour manual erection of process or chemical plants i. piping above ground ii. The most common cutting method is shearing. By contrast a 60 mm round, cold drawn grade 304 steel with same … 45/- per inch dia per metre length. Tube stock; Welding wire/welding rod; Casting; Cutting and burning. Manufacturing is the process of converting raw materials into a finished product, by means of large-scale industrial operations. Standard metal fabrication materials are: Plate metal; Formed and expanded metal. (1) Raw Material Cost Basis: When the historical records of a company reveal that in the past, there was a correlation between raw material costs and factory overheads then they may use a rate as a percentage of raw material cost to absorb production overhead costs into the product or cost unit. Assembly Scrap. Component Scrap 3. 1. 13. Types of Scrap.
