IS 10451:1983 is the Indian Standard (BIS) for steel sliding shutters (top hung type). This standard specifies the requirements for materials, construction, dimensions, and finish for top-hung type steel sliding shutters. It covers the shutter leaves, frame members, top track, rollers, guides, and locking arrangements used in industrial and commercial buildings.

BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Shutter Leaf Sheet Thickness | 1.25 mm (Clause 5.1.1) | Not prescriptively defined; determined by performance requirements like wind load and impact resistance. | EN 13241 |
| Wind Load Resistance | Not specified. Design is based on general engineering practice. | Mandatory classification system (e.g., EN 13241 has Classes 0-5) based on tested resistance to wind pressure. | EN 13241 |
| Hardware Durability | Materials specified (e.g., Mild Steel hangers, Ball Bearings to IS 1238), but no cycle test requirement. | Performance-based grading on endurance testing (e.g., Grade 1 = 100,000 cycles for hangers and track). | ANSI/BHMA A156.14 |
| Safety Against Trapping (Powered) | Not mentioned; standard primarily covers manual doors. | Mandatory. Requires features like reversing safety edges or photoelectric sensors if closing force exceeds specified limits. | AS/NZS 4505 |
| Corrosion Protection | One coat of red oxide zinc chromate primer. | Performance-based requirement, often specified via hours in a neutral salt spray test (ISO 9227) or defined coating systems (e.g., hot-dip galvanizing). | EN 13241 |
| Top Track Material | Structural steel conforming to IS 226 or IS 2062. | Steel, aluminum, or other materials conforming to relevant standards (e.g., EN 10025 for steel), based on load capacity and performance. | EN 13241 |
