De Zinkmeesters & BRL 5212: Craftsmanship under independent supervision

The Zinc Masters: the guild of the finest zinc and copper craftsmen

The Zinkmeesters is a modern guild of specialized craftsmen who have been synonymous with craftsmanship, quality, and reliability in zinc, lead, and copper work for over thirty years. Its members are among the very best in the Netherlands and work in accordance with the industry’s most up-to-date guidelines.

Zinkmeesters are characterized by:

• Skilled and traditional craftsmanship
• High-quality workmanship
• Sustainable use of zinc, copper, and lead.
• Use of modern and proven techniques

The affiliated companies hold the KOMO Process Certificate BRL 5212, which demonstrates their compliance with the established process and implementation standards. SKG-IKOB, as an independent certification body, conducts the periodic assessments and inspections.

BRL 5212, the quality standard for metal roof and facade structures

The BRL 5212 assessment guideline describes the requirements for the professional installation of zinc, copper, and lead roofing, facade, and gutter systems.
The BRL covers several scopes, including:

• BRL 5212-1 – Zinc and Copper Structures
• BRL 5212-2 – Lead Applications
• BRL 5212-3 – Applications to Historic Buildings (including RCE and ERM Guidelines)

SKG-IKOB certifies companies that can demonstrate compliance with these requirements and verifies that the process and end result continue to meet the quality criteria. Certificate holders undergo periodic inspections to maintain their KOMO process certificate.

The relationship between SKG-IKOB and the Zinkmeesters

Zinc contractors consistently adhere to the BRL 5212 guidelines. Members hold the KOMO process certificate, under which SKG-IKOB is responsible for:

• Independent quality assessment
• Regular on-site inspections
• Assessment of the process, craftsmanship, and final result
• Enforcement of the requirements set forth in BRL 5212 and the associated implementation guidelines

As a result, clients can be confident that the work performed by Zinkmeesters meets the highest standards, which are objectively assessed and guaranteed.

Why BRL 5212 is important for clients
