Quality is our promise of performance.
From enquiry to after-sales support, quality is managed as one system across the Schierle Group. Its certified scope is the trade in stainless steel tubes and the consulting and processing services around them.
The certificate is held by Schierle Siyaya GmbH: DIN EN ISO 9001:2015, TÜV Rheinland, reg. no. 01 100 2500992, valid until 2029-06-17. Schierle South Africa aligns its processes with the group quality management system and upholds the same standard.
The group’s system, our daily practice.
The certificate and the policy below belong to Schierle Siyaya GmbH, and its certified scope is the trade in stainless steel tubes. Schierle South Africa is not a separate certificate holder: we run our hydraulic and stainless business to the same quality management system and hold ourselves to the same standard. In practice that means EN 10204 3.1/3.2 inspection certificates, 100% PMI, hardness testing and IGC testing, and full traceability on every order.
