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.

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. 

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. 

Deck Plates - Round, Diamond, Square Pad Eyes
Stainless Steel Deck Plates or Pad Eyes

Diamond Plates, Square Plates, Round Plates, Swivel Plates

Diamond Pad Eye, Square Pad Eye, Round Pad Eye, Swivel Pad Eye

Manufactured from 316 grade stainless steel 

The SBS-450 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. 

The forks are locked into position by tightening the tapered locking nuts using a 'C' pin spanner.

The special tapered locking nuts also hide excessive bar threads.

The forks benefit from 'Double Headed' clevis pins which are fastened into position using a standard 'Allen' key 

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) 

All components are UK produced using the latest CNC technology and are finished to a N4 standard (240 grit satin). Tie bar lengths are available up to 6 metres. Lengths exceeding 6 metres can be catered for by using a tie bar coupler. 

Swageless Fittings - Wire Rope Self Assembly Compression Fittings - Stainless Steel - Fork, Eye, Stud
A complete range of self assembly swageless 'Norseman' type compression rigging terminals, suitable for use with 1x19, 7x19 stainless steel wire rope and Dyform compact strand. Terminate stainless steel wire rope using spanners; without hydraulic presses or swaging machines.

The latest development for compression rigging fittings results in a wire rope termination at least as strong as the rated breaking load of the wire rope.

The unique star shaped Crown Ring positions and holds the wire strands in place, eliminating the requirement for awkward wire end bending.

The shallow angled cone establishes direct mechanical grip on the core and all outer strands.

Stainless steel grade EN10088 1.4404 (316) is used on all parts with the exception of the crown ring which is manufactured from Aluminium Bronze. No sealant or packing is required. 

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.
