MTL Holdings Hires Steve Glasenapp as Director of Envelope

MTL Holdings has hired Steve Glasenapp as the new Director of Envelope. In this role, Glasenapp will work across MTL’s family of brands — Metal-Era, Hickman Edge Systems, and Citadel Architectural Products — to provide strategic customers with a complete metal package for their building envelope.  

Located throughout the United States, the MTL Strategic Accounts team is comprised of experienced industry experts with backgrounds in construction, commercial roofing, and LEED building principles. The SA team partners with contractors, architects, specifiers and building owners to assist in the development of code-compliant building envelopes that protect the most crucial component, the building’s occupants. With the MTL Strategic Accounts team, customers receive solutions for availability, metal color alignment, and strategic purchasing of components traditionally received from multiple vendors, channels, and sources. 

Glasenapp says, “I couldn’t be more excited to be joining the MTL team as the Director of Envelope. A fully tested and engineered system for the exterior metal envelope – from the roof edge to the wall – is not the way the industry traditionally sources the metal package. I’m thrilled to be able to bring a complete solution featuring multiple benefits as a part of an exceptional team and family of brands.”  

Glasenapp has over 15 years of experience in sales and sales management in the manufacturing and construction industry, with a focus on high-design functionality and value-added, code-compliant products. Personally, Glasenapp serves on the Board for Kids Building Wisconsin, whose mission is to bring awareness to careers in the construction industry.
