At the forefront of next generation fastening solutions for concrete

New product developments by EJOT UK ensure the construction industry has access to a wide range of fastening solutions for concrete which offer improved long-term performance and designs that allow for easier use.

The vast array of applications requiring a dependable fixing into concrete has driven the development of numerous innovative fastening solutions. But – as EJOT can demonstrate – there is always the scope to push the boundaries in terms of their technical capabilities, application and performance expectations.

This underpins EJOT’s commitment to R&D, which benefits from the continuous reinvestment of profits to drive new product development, both in the UK and across the EJOT Group.

The latest new products from EJOT represent an important evolution in two of its ranges that are already popular and widely used.

These are the tangible results of proactive programmes led by EJOT’s experienced product designers and engineers to give structural engineers, architects and contractors the opportunity to think differently about the way they attach to concrete.

Upgrades to EJOT UK’s ETA approved through-bolt range

One of these developments is with EJOT’s range of European Technical Assessment (ETA) – approved through-bolts – also known as anchor bolts.

The launch of the BA Plus provides a range of Option 1 anchors suitable for both cracked and non-cracked concrete applications.

It builds on the strengths of EJOT’s established BA range of torque-controlled expansion anchors, suitable for concrete and other hard base materials, including natural stone.

The benefits are extensive, including:

• Quicker to install – the required installation torque can be achieved with 30-50% fewer revolutions than previously.
• Secure in thinner concrete – new M8 and M10 through-bolts can now be used for anchoring in to concrete which is up to 20mm thinner.
• Less risk of installer error – the potential for on-site errors is minimised through a setting depth clearly marked to the thread and anchor length letter coding marked on every bolt head.

BA Plus provides through-bolts for all the most typical cracked and non-cracked concrete applications ≥ C20/25 up to the seismic Option 1 performance. Backed with the independent assurance of ETA approval, the range offers a dependable solution for numerous applications, including steel structures, column base plates, heavy duty racking, cable racks, handrails and facades.

But BA Plus is not the only new through-bolt development by EJOT. Its UK team has also developed a new range of through-bolts for Option 7 non-cracked concrete applications, BA-C NC. This provides a class-leading anchor for many other applications, including warehouse racking and stadium seating – again backed by the third-party assurance of an ETA.

Expanded EJOT concrete screws range offers new application potential

Another major advance comes with the high-performing new additions to the EJOT range of carbon steel concrete screws. These offer greatly extended scope for achieving a secure, reliable attachment for metal fixtures in Option 1 cracked, non-cracked and hollowcore concrete, as well as other hard base materials.

These new developments mean that its JC2 self-tapping concrete screws can be used as an alternative to anchors or screw/nylon plug combinations in an increased range of construction applications. This could include attaching façade scaffolding, shelving and handrails to battens, cable racks and formwork.

Importantly, as these concrete screws need no expansion, they can be used closer to the edge of the concrete and at smaller spacings than when using anchors. They are also easy to use and install, with no specialist skills required, which can be a big time-saver on site.

Only a small pilot hole is required, which generates a relatively small amount of dust. Once this is removed from the hole, the screws are simply driven into place – they are completely removable and relocatable, like a standard wood or metal screw, which makes them a versatile choice.

The JC2 range offers six fastener types designed by EJOT’s R&D teams in both Germany and the UK, to offer superior performance in-situ along with hassle-free installation. All provide the independent assurance of ETA approval and are tested to offer fire resistance to 120 minutes.

A trusted UK-focused concrete fastening systems partner

Five galvanised or zinc alloy coated carbon steel concrete screws form the core product range, but EJOT has also developed a sixth option specifically to meet the needs of the UK market. This ETA-approved fastener with enhanced corrosion resistance is the JC6-KB, a bi-metallic concrete screw manufactured in A4 316 stainless steel with hardened carbon steel lead threads.

As a result, the JC6-KB is suitable for outdoor Option 1 concrete applications approved for environmental classifications ranging from C1 up to C4, in accordance with BS EN 12944.

Its development reflects how the UK R&D team, supported by the EJOT Group team in Germany, is ideally positioned to ensure local customers have the right products they need to apply in the way they prefer. The overall EJOT product portfolio may be designed to suit a global market, but that does not mean UK customers have to adapt the way they work when choosing the EJOT brand.

In fact, the team in Sherburn-in-Elmet is proactively developing UK-focused fasteners that are gaining traction in overseas markets too, making a positive contribution to the global construction market. This benefits from the EJOT strength that brings together the best of British and German engineering – an internationally respected combination.
