ZS2 doesn’t just meet industry standards; they set them. By heavily investing in testing and certifications, ZS2 can confidently and safely bring innovative constructions to market that seamlessly integrate into existing regulations and industry standards.
They’ve built rigorous Quality Assurance (QA) and Quality Control (QC) procedures into their manufacturing processes to ensure streamlined delivery from production to construction. This ensures that their building materials undergo rigorous assessments to guarantee enhanced durability, resilience, and long-term performance in diverse environmental conditions. This proactive approach minimizes the risk of failures, enhances safety, and protects the investments made in construction projects.
ZS2's team proudly collaborates with QAI Laboratories (QAI) for testing, certification, and Code Evaluation Reports for ZS2 building products. From inspecting their manufacturing equipment to batch testing their TechBoard before panel assembly, QAI acts as an independent third-party testing, inspection and certification organization to ensure transparency at every step of the process.
QAI services are accredited by numerous, respected international accreditation bodies including the International Accreditation Services (IAS) and the Standards Council of Canada (SCC).
This ensures all ZS2 products that arrive on site meet and exceed project requirements.
