Architectural Tie Bars

The s3i stainless steel tie bar/tie rod system is made from high tensile materials resulting in extra strength and has a tapered lock nut design feature that hides bar threads thus providing a clean cosmetic appearance.

The standard tie bar system consists of a bar with a left hand and right hand threaded SBS-450 fork at each end.

Once installed the rod can be rotated to expand or contract the fork's pin centres. Special spanner flats can be added to the tie bars to help with rotation.

SBS-450 forks and pins are manufactured from Duplex grade stainless steel. This offers high resistance to corrosion and superior mechanical properties over marine grade 316 (EN10088 1.4401)

We have a wide range of experience with tie bar systems and can offer assistance to architects, designers, project managers and the end user.

Wire Trellis System

Green Wall Stainless Steel Trellis

The 'Green Wall' stainless steel trellis system is made up of a clever stainless steel wire hub allowing the crossing and partial tensioning of wires to form trellis sections.

A green facade has the ability to transform the outer skin of our cities into a living landscape, allowing the concrete and brick to become environmental assets themselves.

As consumers we place a high value on areas that incorporate pockets of green. We can create more desirable places to live and work by cloaking some of our urban landscape with a living tapestry.

Stainless Steel Carbine Hook

Carbine Hooks - Stainless Steel, Marine Grade 316

Also referred to as a Carabiner or Karabiner - this stainless steel carbine hook has a sprung gate and it can quickly and reversibly connect components in safety-critical systems, such as in industrial access work.

Carbine hooks also available with a screw lock gate.

When used for access in commercial and industrial environments within Europe carabiners must comply with EN 362:2004 'Personal protective equipment against falls from a height. Connectors'.

Locking carabiners have the same general shape as non-locking carabiners, but have an additional sleeve around the gate. The sleeve can be released along the gate and, when it is at one end of the gate, cannot be opened (except by releasing the sleeve and moving it to the other end of the gate).

This provides security against the carabiner opening accidentally, for example, if struck against a rock or if caught in a loop of rope. The sleeve can be either auto-locking or a twist-lock.

Wire Rope Grips

Wire Rope Grip in 316 grade stainless steel
Wire rope grips (bulldog grips) require no special tools for assembly and can be disassembled and reused.

Simplex and Duplex wire rope clip thimbles. Used to create eyes in 2mm - 8mm 7x7 & 7x19 cable constructions. Simply loop the cable each side of the threaded bolt and tighten down the plate using a suitable spanner.

Simplex and duplex wire rope grips are not suitable for use with any 1x19 construction cables and also not suitable for lifting applications. 

Wire Rope Grips

Wire Rope End Fittings

Swage Wire Terminals for Stainless Steel Wire Rope - Swage Fork, Swage Stud, Swage Eye, and Swage Toggle.
Swage rigging fittings are pressed onto wire rope strand with a swaging machine, providing a termination at least as strong as 1x19 strands.

Swage wire fittings can be used to terminate 1x19, 7x7 and 7x19 wire strands.

Stainless steel swage wire fittings can also be used with dyform or compact strand, but special consideration should be given to the application. Please call us to discuss any special requirements.

'Swaging' is a process of moving metal. It is important that swage fittings/terminals are swaged down to the correct diameter.

Super Duplex Stainless Steel

The atmosphere of indoor pools is one of the most aggressive environments to be found in building applications. High water temperatures, combined with increasing usage has resulted in higher levels of chlorine based disinfection being used.

These disinfectants react with contaminants to produce chloramines which are considered to be the most important factor in the corrosion of stainless steel in these pool environments. Higher air temperatures also significantly accelerate corrosion.

Higher levels of humidity as a result of increased water turbulence lead to increased condensation in cooler parts of the buildings, and during cooler night time periods.

Repeated drying out and re-condensing of the chlorine rich water vapour results in very aggressive build up of chlorine species which can produce a highly corrosive film, leading to accelerated stress corrosion cracking.

The components within indoor pools most likely to be affected are ceiling wires and rods, water ride or flume support cables, structural fasteners, cable strapping, brackets and cables for lighting units, supports for suspended ceilings, rod and bar supports for ventilation ducting.

Since 1985 there have been tests carried out and recommendations made, that promote the use of super duplex grades of stainless steel for these specific safety critical applications.

S3i can manufacture fittings, shackles and wire rope assemblies from super duplex stainless steel.
