Solar Equipment Manufacturers

Williams Form Engineering Corp.

The Williams story began in 1922 when Mr. C. I. Williams graduated from Michigan State University with a degree in Civil Engineering. He immediately took a job with the State of Michigan as a bridge inspector. It was not long until Mr. Williams realized the industry desperately needed an improved system for pouring concrete. By the late 1920's he had developed a concept for a detachable forming system which he called the "Shebolt" system. Mr. Williams quit his job as a bridge inspector, bought some equipment and began manufacturing his new product.

Solar Stainless Fasteners


In the 1980's, stainless steel fasteners were sometimes difficult to come by. Except for a few major importers that supplied distributors, inventory was not readily available. Carl Brantley realized stainless steel would never gain wide spread acceptance in the US market place as long as this system kept the pricing out of reach for the average consumer. His plan - to invest heavily in imported stainless steel and sell directly to the OEM. In 1984, he opened Marine Fasteners.
