Ancon STS Connector

Ancon STS/SSTS Connector

Ancon STS (galvanised steel) and SSTS (stainless steel) are compact thermal breaks, typically used for connecting steel balconies to structural steel frames. They are also equally suitable for other steel-to-steel applications.

The connectors comprise tension and compression components within a single combined unit, wrapped in class A1 non-combustible mineral wool insulation. Manufactured to order, the vertical centres of the four A4 stainless steel fixing studs can be specified to suit the exact requirements of an application.

A thermal plate, with an independently verified European reaction-to fire classification of A2-s1 d0, is located at each steel interface.

Thermal Modelling

Thermal modelling of a typical application showed a reduction in heat loss of almost 50% compared to a direct steel connection. It also illustrated a temperature factor within the limits detailed in BRE document IP1/06 for eliminating condensation risks in buildings of any type, even those with high humidity e.g. swimming pools (0.90).

UKCA and CE Marking

STS (hot dipped galvanised steel) and SSTS (stainless steel) connectors are designed to EN 1993 (Eurocode 3) and UKCA and CE marked to BS EN 1090 Part 1. 

System Benefits

  • Comprises materials of class A1/A2 combustibility only, ideal for high-rise construction
  • Proven through thermal modelling to reduce heat loss and eliminate condensation risk
  • Thermal pad located at each steel interface
  • Bracket fabrication UKCA and CE marked to BS EN 1090-1
  • Variable fixing heights to suit application
  • In the case of SSTS, fully stainless steel components offer the ultimate corrosion protection and thermal efficiency benefits

CE, UKCA and CE UKNI marking from Leviat

From January 1st 2021, the UK will recognise both the EU CE marking approvals, for a time limited period, and the new UK based approval system, which will be known as the UKCA mark. The EU will only recognise CE marking by EU notified bodies as proof of efficacy moving forwards. Leviat has been working closely with both EU notified and UK approved bodies to ensure compliance is achieved at the earliest possible opportunity and we can confirm that we have obtained all relevant certification.
