Structure
The standard covers steel doors, windows, ventilators, and fixed lights including fabrication, sampling, glazing, and fixing requirements. Sampling scales are based on lot sizes with defined sample sizes and allowable defectives. Glass sizes and glazing clip quantities are specified per unit type. Purchasers provide detailed specifications including type, fixing method, hinges, fittings, mullion/transom details, fly-proof screen needs, shutter operation direction, finish, and glazing bead preferences. Additional notes include weather bar mass and rounding off procedures as per IS 2-1960.
Defines terminology related to sampling scale, purchaser information requirements, glass sizes, and glazing clips. Emphasizes rounding off data according to IS 2-1960. Sampling flowchart illustrates sample size selection based on lot size.
Explains the designation system for doors, windows, and ventilators by width, type, and height modules. Type letters indicate shutter style and glazing bar presence. The direction of closing follows IS 4043-1969, specifying left-hand leaf closure for double doors and concealed bolts to avoid sagging. Includes standard size clearances and a summary of type letter meanings.
Details standard sizes for steel fenestration units as per figures, with tolerances of ±1.5 mm for frame dimensions. Designations follow a coded system indicating type and size, with corresponding glass sizes and number of glazing clips specified. References to IS 4043-1969 for direction and IS 2835:1987 for steel section standards are included.
Requires rolled steel sections conforming to IS 7452-1982 for fabrication of steel doors, windows, ventilators, and fixed lights. Glass sizes with clearance allowances are specified alongside glazing clip quantities. Fabricated weather bars have a mass of 1.8 kg per meter. Dimensions and materials are strictly defined to ensure quality and durability.
Specifies construction details for steel fenestration units, including weather bar fabrication, glass sizes, glazing clips, and overall assembly as illustrated in figures. Emphasizes use of rolled steel sections and adherence to dimensional and fabrication guidelines.
Outlines fixing methods including screw sizes and types for different substrates (wood, concrete, brick, steel). Details slotted fixing lugs and fixing clips for steel work, surface treatment requirements such as hot-dip galvanizing with minimum zinc coating, and painting procedures. Fixing hole locations and lug quantities are referenced.
Describes pretreatment of steel surfaces by mechanical or chemical means, phosphating, primer application, and drying methods. Hot dip galvanizing standards specify zinc coating thickness. Various painting techniques including brushing, spraying, and dipping are outlined with relevant IS standards.
Sets minimum glass thickness at 3 mm per IS 2835:1987, requiring squared corners and straight edges. Glass sizes and number of glazing clips per pane are listed by designation. Glazing clips are standard for putty glazing and fixed according to specified clauses.
Sampling protocols based on lot sizes include sample and sub-sample sizes with maximum allowable defectives. Inspection and conformity requirements ensure quality control. Purchasers must provide detailed specifications to aid accurate sampling and production.
Outlines essential information purchasers must submit when ordering steel fenestration components, including type, size, fixing medium, hinge type, fittings, mullion/transom details, fly-proof screen requirement, shutter operation direction, finish type, glazing bead preference, and any other relevant notes.
Describes sampling methods based on lot size with defined sample sizes and permissible defects. Emphasizes independent lot inspection and purchaser-supplied data for accurate sampling and manufacturing.
Includes reference to standard sizes, glass sizes, glazing clips, and detailed hardware specifications such as handles made from brass, aluminum, or treated steel, hinge types (projecting, non-projecting, self-aligning), kick panel construction, and fabricated weather bar details.
Frequently Asked
IS 1038 specifies that steel doors, windows, ventilators, and fixed lights use rolled steel sections conforming to IS 7452-1982. Glass panes must be at least 3 mm thick per IS 2835-1977. A uniform clearance of 10 mm is recommended around openings for proper fitting. Welding joints can be made by any method provided they meet quality standards. Detailed sizes and tolerances are outlined in Table 1 of the standard.
The standard requires rolled steel sections that meet IS 7452-1982 for structural components of steel doors, windows, ventilators, and fixed lights. Steel used must also comply with IS 7452-1982. Kick panels are fabricated from 1.25 mm mild steel sheets in double tray construction, attached by welding or screwing. Hinges include 50 mm projecting steel types, non-projecting, and self-aligning variants, with pins and washers made from galvanized steel or aluminum alloy.
While IS 1038 does not explicitly list welding test procedures, it mandates that welding processes be identified and that fabricated units meet quality criteria. Common tests include visual inspections for defects, fillet weld size measurements, destructive tests like bend and tensile tests on samples, and non-destructive tests such as dye penetrant and ultrasonic inspections. These ensure compliance with fabrication standards and structural integrity.
Glazing must use glass panes with a minimum thickness of 3 mm, conforming to IS 2835:1987, possessing squared corners and straight edges. Glass sizes vary by door or window designation as per Table 1, with clearance allowances for fitting. Glazing is installed on the outside face of frames. Spring glazing clips secure glass panes larger than 600 x 300 mm, spaced not more than 300 mm apart. For bead glazing, aluminum or steel channel beads fixed with screws and backed with putty or rubber are used without clips.
IS 1038 does not explicitly specify hardware fittings or locking mechanisms for steel doors, windows, ventilators, or fixed lights, particularly for industrial buildings. It advises that purchaser and manufacturer agree on specific requirements. Fixing hardware details are referenced to IS 1081-1960. Typical hardware such as mortise locks, night latches, espagnolette bolts, and tower bolts are not covered by this standard but can be sourced from relevant standards or manufacturer catalogs.
