Special fasteners for steel construction and infrastructure
CE-marked bolting assemblies, anchor bolts and large-diameter bolts for bridges, tunnels and industrial buildings
Industry we can supply
CE-marked bolting assemblies, anchor bolts and large-diameter bolts for bridges, tunnels and industrial buildings
In steel construction and infrastructure, documented proof is what counts: bolt, nut and washer assemblies for load-bearing steel structures require CE marking to EN 15048-1 with a Declaration of Performance, while anchor bolts and large-diameter bolts for bridges, tunnels, industrial buildings, masts and power plant structures require material verification with a certificate. RS Randack is certified by a notified body for assemblies to EN 15048-1 and also manufactures special bolts, anchor bolts and threaded rods to drawing in large sizes.
Typical parts
- Non-preloaded structural bolting assemblies to EN 15048-1 in property classes 8.8 and 10.9, CE-marked with Declaration of Performance
- Anchor bolts, foundation anchors and threaded rods with rolled threads, typically up to M180 and 3,500 mm in length
- Large-diameter bolts and special bolts for bridge bearings, tunnel boring machines, locks and weirs
- T-head bolts for anchor channels, special heads from our own forge
- Nuts, jam nuts and washers to match the bolt, hot-dip galvanised or with zinc flake coating
Requirements and documentation
- CE marking under the Construction Products Regulation with Declaration of Performance and factory production control, subject to annual surveillance
- Material verification with inspection certificate 3.1, property class tested on the test bar, impact energy for components in cold environments
- Corrosion protection by hot-dip galvanising with thread allowance or zinc flake systems; see Surface treatment
- Batch documentation per line item for site supervision and structural verification
