M-D AT A GLANCE
Quality and Innovation
It was a simple – but revolutionary – first. L.A. Macklanburg, frustrated with the dust and dirt blowing in under his door, created the first form of weatherstripping-inspiring not only a solution, but a business. It was symbolic of the smart, refreshingly uncomplicated thinking that continues to define M-D Building Products today: quality that never wavers and innovation that never stands still.
A family-owned business with more than 90% of our products manufactured in North America, we stand apart in our ability to maintain higher standards of quality control, respond faster to changing market conditions and meet customer demand with greater speed and efficiency.
Consumers and industry professionals throughout the world trust our products and services – positioning us as the leaders in the weatherstripping, floor and tile trims, perforated aluminum sheets, digital levels, and caulking categories. Additionally, thousands of manufacturers rely on our custom aluminum and vinyl extrusion businesses to build the quality components upon which they can confidently put their name.
