    “We use STS mainly for wedge clips and anchor wedge barrels in the construction of shoring walls in basements.  We’ve used them for numerous high rise residential buildings across Sydney, and most recently for the new Bunnings building at Kings Grove.

    We’ve visited the STS head office and and warehouse in Sydney, which allowed us to see for ourselves the level of their quality control.  We have peace of mind that STS products are reliable (and still competitively priced), and the service we get from their team is consistently great too.”

    “We’ve been dealing with STS for a number of years and I feel like our businesses have grown together.  We use their anchors, blocks and wedges, and more recently they’ve expanded their range so we’re now also buying ducting and grout pumps from them. For PTC, we see STS as our ‘one-stop-shop’ – every week the delivery truck arrives with everything we need for post tensioning slabs.

    The relationship we have with STS is solid, and importantly the quality and reliability of their products and customer service is totally reliable. We’ve never had any problems.”

    “I’ve worked on many large construction projects using the STS anchorage systems (castings, wedges, barrels, and anchor blocks).  These systems have been used in post tensioning of concrete floors in numerous buildings across Perth, including the new Crown Towers Casino, Pinnacles Apartments and 500 Hay Street.
    I’ve had a relationship with Severs for many years, and with the company growing into STS in more recent times, they continue to deliver with good service and reliability of their products. Everything I use from STS is tested by engineers to Australian standards so there’s never an issue with trusting their quality.”
