Black steel finish offers cost saving opportunities for customers
TSS Stair Landing Connectors are now available in a default black steel finish, which will benefit our customers and the environment.
High material, energy and labour costs are challenging the construction industry. Consequently, Invisible Connections has been looking at ways to make efficiencies – and pass these savings onto customers.
One way we can achieve this is by supplying our range of TSS telescopic connectors in a default black finish. Hot dip galvanised (HDG) options will continue to be available – and we’ll ask customers to confirm their preference at time of order placement.
Why the change?
Traditionally, HDG has been the default finish for cord-operated TSS telescopic connectors. This was principally to help prevent the wire rope from jamming, in case outside storage might cause a rust interlock to form inside the connector. An HDG finish also helps resist potential staining, as well as providing protection in rare external applications.
However, a few years ago, we introduced the pinned TSS telescopic connector, the TSS 81-30 PIN, which was only available in a black finish, and which also had a new-generation wire loop for easier deployment. Pinned TSS connectors tie and support stair landings (meeting PD6687-1 anchorage requirements) where only one or two core walls are available for the connection, whilst also ensuring a blemish-free finish on the top surface of the landing.
Many thousands of TSS 81-30 PIN connectors have been used on a wide range of projects: ‘Nova Evolved’, the ‘Berners Wells Building’ and ‘Victoria & Albert Museum East’, to name a few. Positive customer feedback has given us confidence that the default finish for all TSS connectors can be black, not HDG.
More choice means more cost saving opportunities
One advantage of a black finish is a significant manufacturing cost saving. For example, for the TSS 101 STD there is a cost saving of 7.5%, which we’re passing onto customers. HDG pricing will remain unchanged.
Reducing resource consumption and environmental burden
In general, hot-dip galvanising is regarded as the most economical way to protect iron and steel against rust, and ensures a long, maintenance-free service life. At Invisible Connections, our galvanisers obtain zinc from secondary sources to minimise environmental impact. Nevertheless, the galvanising process involves intensive consumption of energy and resources.
By offering a black finish as standard, we’re cutting our consumption of secondary zinc and hydro-electricity, as well as decreasing the generation and disposal of residues produced during the galvanising process. As a result, we’re reducing the environmental burden and contributing to more sustainable manufacturing practices.
All the materials used in manufacturing telescopic connectors are recycled or recyclable. The telescopic connectors are manufactured in Norway using clean hydro-electric power from local waterfalls.
New product features and new variants
We’re currently rolling out new features to both our TSS and RVK range of stair landing connectors. We’re also introducing two new variants.
For example, TSS connectors now incorporate a redesigned wire loop (as previously mentioned), which greatly improves functionality when ejecting the inner tubes on site – and means inner tubes can be deployed on site from above or below the landing. And our new TSS and RVK ‘JCK’ variants, used in combination with a compatibly modified REDiBOX, means landings can be raised or lowered to level without shimming. All of which makes life even easier for frame contractors when installing precast stair landings.
