Roof Replacement – Gerdau

April 14, 2016

BETAC is working in conjunction with Hatch’s Structural Consultant in Winnipeg for Gerdau Ameristeel Corporation. Gerdau is undertaking a major renovation of one of its buildings, the Melt Shop Facility at its Manitoba Mill located in Selkirk, MB.

Background

The building in question houses an industrial process with extreme process conditions (heat, particulate matter, corrosive materials) and is subject to a planned roof replacement.

The current roof has reached its intended life service target of fifty years, however the interior and exterior has corroded substantially. This has resulted in increasing heat loss in the winter as well as water ingress into the building.

Our Services

The research undertaken by BETAC addressed the building and material science uncertainties created by the extreme conditions from the industrial process and Manitoba climate.

Results

The final project report addresses the mechanisms that led to the roof damage, as well as the various design and maintenance considerations for this particular building that is subject to such extreme internal and external conditions.
