Custom Access Hardware Manufacturing

Our catalog is extensive and features more than 4,000 hardware products, but if you’re looking for custom hardware to meet a specific need, we regularly work with customers to design, patent and manufacture custom industrial hardware. SPEP has accumulated more than 80 patents over the years, many of which resulted from collaborations with our customers.

We’re proud to employ a team of world-class engineers ready to work closely with our customers, and we’ve implemented numerous technologies and processes to streamline the custom manufacturing process. The SolidWorks 3D CAD system allows us to maximize productivity and speed up design times, while Finite Element Analysis (FEA) allows our engineers to precisely predict how a product will function in real-world conditions.

Finally, we use advanced fused deposition prototyping machines (3D printers) that let us design a product, create a proof-of-concept on a computer, and quickly produce physical models from ABS plastic in real time. This makes it easy to design a new part and test it quickly, speeding up the design process and ensuring you are 100% satisfied.

We use the Oracle Quality module and E-Business Suite for paperless operations and maximum efficiency, and our warehouses and shop floor are completely automated. Every workstation and forklift is directly connected to our ERP system in real time, meaning orders get in quickly, update automatically, and can be tracked in real time.

SPEP has been 100% employee-owned (100% ESOP) since 2005, meaning every employee is truly a member of our family and personally motivated to provide an incredible experience for our customers.
