Seismic design in construction can add complexity and cost. To simplify this, ICCONS® has proudly developed the shallowest C2 seismic concrete Screw-Bolt in Australia. Part of the Thunderbolt®PRO range, the SXTB08055 offers innovative performance, cost efficiency, and ease of installation.
KEY FEATURES:
● Outstanding Performance: Assessed for Cracked Concrete, Fire, C1, and C2 seismic approvals.
● Cost-Effective: Reduces fixing costs compared to typical seismic C2 assessed anchors.
● Labour-Saving: Requires only 50mm concrete embedment for rapid installation.
● Versatility: Available in Hex, Countersunk, Pan, Internal, and External Metric Thread head styles.
● Durable Finishes: Options include Zinc, Nautilus C or Mechanically Galvanised coatings for corrosion resistance.
THE EVOLUTION OF SEISMIC STANDARDS IN AUSTRALIA
Australia’s building codes have become more stringent to enhance seismic safety. Standards like AS 1170.4-2007 and AS 5216:2021 ensure structural integrity during earthquakes. AS 5216:2021 includes guidelines for post-installed fasteners under seismic actions, with performance categories C1 and C2.
● C1 Seismic Anchors: Suitable for moderate seismic zones with limited concrete cracking (≤ 0.5mm), ideal for residential and low importance level buildings (See National Construction Code: Part B1 Structural Provisions (DtS)).
● C2 Seismic Anchors: Designed for high-risk zones with greater concrete cracking (≤ 0.8mm). These anchors are essential for critical applications like structural elements, mechanical services, and emergency facilities in higher importance level buildings (See National Construction Code: Part B1 Structural Provisions (DtS)).
WHAT SETS C1 AND C2SEISMIC ANCHORS APART?
C1 Seismic tests focus on tension and shear loads under moderate conditions, while C2 Seismic tests add rigorous reference and alternating load tests, accommodating wider concrete cracks (0.1mm to 0.8mm). The severe testing makes C2 anchors crucial for safety critical applications in high building importance level or earthquake-prone regions.
WHY CHOOSE THE THUNDERBOLT®PRO RANGE?
ICCONS’ SXTB08055 C2 seismic Screw-Bolt stands out with its shallow embedment, increasing productivity without compromising safety. It is:
● AS 5216 compliant, Fire rated and Seismic C1 and C2 assessed
● European Technical Assessment
● Designed for ‘close to edge’ applications with low expansion forces, and easy removal.
Ideal for applications including seismic bracing, wall systems, and fire-rated fixings.
SUMMARY
As seismic safety standards evolve, selecting the right anchor is critical for compliance and structural integrity. The Thunderbolt®PRO SXTB08055 offers an industry-first solution as the shallowest C2 seismic Screw-Bolt in Australia, delivering unmatched performance, versatility, and ease of use.
