Design & Engineering

HAZ Metal provides services in the design of fixing systems and the preparation of structural calculations. This service is done in the company technical department using CAD software and stress analysis programs.

Our technical team receives the necessary technical information of the project in order to propose the most suitable, secure, easy to use and economical fixing systems in accordance with the project criteria. Custom design is also made in accordance with the architectural drawings of the project. Please contact us with any queries.

HAZ Metal provides the necessary technical documentation for submittal to the project officials in order to receive approval for the fixing system elements. The following principles are used in the design and structural calculations for natural stone fixing systems.

Finite element stress analysis is implemented for complex structures where the structural integrity of the fixing systems needs to be maintained. This procedure is especially made for sub channel systems and unitised panel facade units.

HAZ Metal can offer the design and engineering services by referring to any internationally renown standards. The engineering department will relate to the specifications of the project and conduct its design and dimensioning according to the requested criteria.
