Inner corner for fire-resistant duct

Inner Corner for Fire-Resistant Duct – Technical Overview and Supply

Block 1: Technical Introduction
Inner corners for fire-resistant ducts are essential components designed to maintain the integrity of cable management systems in fire-critical environments. These fittings are typically manufactured from galvanized steel or stainless steel, with thicknesses ranging from 1.0 mm to 2.0 mm, ensuring mechanical strength and corrosion resistance. They are engineered to connect duct sections at 90-degree angles, preserving the fire-resistant properties of the overall system. Key technical parameters include compatibility with duct widths from 100 mm to 600 mm, and they often feature pre-punched holes for secure mounting with M6 or M8 bolts. The inner corner design ensures a smooth transition for cables, minimizing bending radius issues and maintaining the required fire rating (e.g., up to 120 minutes according to EN 1366-1). These components are part of a broader category of fire-resistant cable management accessories, including straight sections, tees, and reducers.

Block 2: Applications and Sectors
Inner corners for fire-resistant ducts are primarily installed in electrical distribution panels, control cabinets, and automation systems where fire safety is paramount. They are widely used in commercial buildings, industrial plants, data centers, and infrastructure projects such as tunnels and airports. In these environments, they ensure that cable pathways remain intact during a fire, preventing the spread of flames and smoke. The components are also critical in sectors like oil and gas, pharmaceuticals, and transportation, where compliance with strict fire codes (e.g., NFPA 70, IEC 60364) is mandatory. Their installation in vertical or horizontal runs within cable trays or ladder racks supports organized cable routing and facilitates maintenance access.

Block 3: Subcategories and Key Articles
This category includes various subcategories such as inner corners for standard fire-resistant ducts, heavy-duty versions for industrial applications, and adjustable models for custom angles. Key article codes often follow a pattern like "IC-FRD-100" for a 100 mm width inner corner, where "IC" denotes inner corner, "FRD" indicates fire-resistant duct, and the number specifies the duct width. Other common codes include "IC-FRD-200" and "IC-FRD-400", with variations for different material finishes (e.g., galvanized or stainless steel). These articles are typically available in standard lengths of 300 mm or 500 mm, with optional accessories like sealing gaskets or mounting brackets.
