STEEL CLAMPING SYSTEMS / FIRE RATED SUPPORT FIXINGS

Lindapter Type FL312D Beam Flange Clamp (13mm Clear Hole)

The Lindapter Type FL312D is a heavy-duty structural component celebrated as part of the industry's only independently fire-rated beam flange clamp family. Expertly manufactured from robust malleable iron with a high-grade zinc-plated finish, this structural clamp is purpose-engineered to secure essential building services directly to parallel or tapered beam steelwork without requiring on-site drilling or welding. Featuring a clean 13mm diameter rear clear hole designed to accept M12 threaded rods, it serves as an invaluable, non-destructive anchoring point across mid-to-heavy commercial pipework suspended arrays, fire protection sprinkler systems, HVAC assemblies, and cable management trays.

CRITICAL STRUCTURAL MANDATE: CALIBRATED TORQUE & INSTALLATION

To maintain complete compliance with accredited engineering safety factors, the integrated M10 cup-point setscrew must be adjusted finger-tight and then applied exactly a further quarter-turn (90°) with a spanner (8 Nm). Following this, the primary security locknut must be fully balanced and secured using a calibrated torque wrench to exactly 22 Nm. On tapered structural steel profiles, ensure the cup-point setscrew grips securely onto the inner face of the flange. For installations supporting pipework with a bore exceeding 65mm, an additional Lindapter safety strip must be integrated to fully comply with specialized VdS compliance parameters.

How We Keep Your Builds Moving

We operate our own dedicated logistics vans out of Luton alongside leading national freight carriers, ensuring full trace visibility from our warehouse shelves straight to site.

01.

Instant Hub Sorting: Approved orders pass straight to active pick queues via our localised automated barcode stock framework.

02.

Heavy Component Packing: Structural products are safely stored in industrial reinforced cartons or strapped securely to pallets to fully safeguard fine threads and anti-corrosion zinc surfaces.

03.

Tailgate On-Site Offloading: Bulk shipments drop cleanly at your structural site boundary line via integrated tail-lift carrier transport systems.

Logistics Scope & Out-Of-Zone Shipments

Standard courier pricing arrays map explicitly to structural mainland UK postal grids. Supplementary transit routing variables, variable lead times, or specialised carrier adjustments apply across high-altitude or outlying maritime zones:

Scottish Highlands & Islands: Postcode structures matching KW, IV, PA, and PH configurations map to alternative transit grids. Please review checkout calculations for accurate real-time weights.
Northern Ireland, Isle of Man & Channel Islands: Water-crossing logistical paths require clean custom manifesting lines.
Heavy Oversized Pallets: Extended multi-ply girder connectors, structural space straps, 3m channel unistrut, or high-volume masonry hangers pass through dedicated heavy haulage grids.
