Let us take you on a "tour" of our 40,000 square foot manufacturing facility located in Buffalo, NY where we serve our customer's sheet metal needs locally, nationally and internationally since 1968!

Quite simply, we begin with the customer in mind. The ATECH-SEH motto has always been "a quality part, delivered on time, every time." Our engineering department begins the review of customer requests by utilizing PDF prints provided, as well as implementing Solid Works, Cadman-B and Autocad programs as called for by the job at hand. Your part is made to print using the very latest in engineering technology.


What types of parts can be made at ATECH-SEH? We can provide parts from the size of a "quarter" to a steel door frame which could be 8' or 10' high by 6' wide. The possibilities are endless and are as diverse as our customers, who represent multiple businesses in the electronic, telecom, transportation, architectural, display and medical industries.

Quality is assured and checked at each step along the ATECH-SEH manufacturing process. A packet with your part print and specific instructions leads your order to completion.
