HOW TO FASTEN ELECTRICAL EQUIPMENT TO STEEL

Fixing electrical boxes, cable ladders, cable trays, brackets and more

Hilti fastening solutions for fastening electrical equipment to steel

Steel base materials are usually pre-coated before they’re shipped to the jobsite, to protect against corrosion.

So, the challenge while fastening electrical boxes, brackets and other electrical instruments, is how to mount them to steel without damaging its protective coating.

To solve this, we’ve developed Hilti X-BT in stainless steel and Hilti S-BT studs, in duplex-coated carbon steel and stainless steel.

They’re compatible with Hilti’s modular support systems and are used in steel buildings worldwide, from skyscrapers to offshore platforms.

Use them to secure electrical panels, cable trays and ladders, electrical boxes, switch cables, cable tray supports and cable ladder supports.

THE ADVANTAGES OF HILTI FASTENERS FOR STEEL

Our fasteners for steel are tried and tested

The Hilti X-BT has been used on some of the world’s toughest jobsites for more than 15 years. All our fastening technology is backed up by more than 75 years of Hilti engineering innovation.

Key features:

Resistant to vibration
Resistant to corrosion in C3 medium corrosive environments and C5 highly corrosive environments
Works in a wide range of temperatures from -40 °C to +100 °C
Comes with Type Approvals – so you can use them in projects worldwide
Get help with your calculations – we provide recommended load values to help you work out how many fasteners you need. See more details in our Direct Fastening Technical (DFTM) Manual and the Hilti X-BT Threaded Fastener Specification

Our fasteners are designed to not damage protective coatings – and to be quick to install

Developed to speed up work on the jobsite, without the need for clamping, through bolting and welding - with no need for specialist trade skills such as welding
No need for power cables – use with the Hilti SF BT-22A cordless drill
Avoid rework – the Hilti X-BT and Hilti S-BT are designed to keep corrosion coatings intact on the steel base material during installation. They also come with an integral sealing washer, which protects against corrosion.
