STEEL CLAMPING SYSTEMS / FIRE RATED SUPPORT FIXINGS

Lindapter Type FL412D Beam Flange Clamp (13mm Clear Hole)

The Lindapter Type FL412D 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 features an extended jaw architecture specifically engineered to accommodate deeper steel profiles. It allows you 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 M10 threaded rods, it serves as an invaluable, non-destructive anchoring point across mid-to-heavy commercial pipework suspended arrays, fire protection installations, HVAC assemblies, and structural framing.

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.

KEY STRUCTURAL PERFORMANCE ADVANTAGES

  • ISO 834 Fire Rated Verification: Independently tested and verified under severe thermal conditions to withstand building service loads during fire emergencies.
  • Zero Welding & Drilling: Preserves the fundamental integrity and protective engineered surface treatments of the structural beams on-site.
  • Parallel or Tapered Universal Fit: Robust malleable iron jaw layout accommodates seamless clamping adaptation across diverse structural profiles.
  • Pre-Galvanised Surface Defense: High-durability zinc protection layer serves as an effective barrier against standard architectural moisture tracking.

How We Keep Your Builds Moving

We partner with leading heavy industrial parcel and parcel-freight carriers across the country to maintain real-time tracking from our central warehouse shelves straight to your signature pad.

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 crates or strapped securely to custom 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 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 premium alternative transit grids. Please review checkout calculations for accurate real-time weights.
  • Northern Ireland, Isle of Man & Outer Channels: Specialised water-crossing logistical paths require clean custom manifesting lines.
  • Heavy Oversized Pallets: Extended multi-ply girder connectors, structural space straps, or high-volume masonry hangers exceeding standard bulk dimensions pass through dedicated heavy haulage grids.
*** NEED SPECIFIC AM DELIVERY TIMES OR SITE COORDINATION ARRANGEMENTS *** If your project features demanding time windows, unique site restrictions, or crane offload coordination, contact our central logistics team directly on 01707 375172 or email your schedule over to finalise arrangements.
