San Antonio shops build trailers, weld up structural packages and machine parts for the aircraft work at Port San Antonio. Winston Materials sources the steel, aluminum and stainless behind that work and delivers it, cut to size, from our base in Dripping Springs. We don't have a San Antonio branch or yard. You get one contact, one quote and material brought to your door.
Delivery coverage around San Antonio
We deliver across Bexar County and up the I-35 corridor through Schertz and New Braunfels, east on I-10 to Seguin, and northwest on I-10 to Boerne. Shops inside Loop 410 or out on Loop 1604 are covered the same way, and so are fab shops south of town that serve the Eagle Ford Shale.
Delivery is sized to the order. Trailer tube in 24-foot lengths moves differently from a box of cut plate, so the quote shows how it's coming before you sign off. If you need it dropped at a job site instead of the shop, say so on the RFQ.
San Antonio industries we supply
Port San Antonio, the former Kelly Air Force Base, is a center for aircraft maintenance, repair and overhaul, and that pulls in machine shops making tooling, fixtures and ground support parts. That work usually wants 6061 and 7075 aluminum plate with clean traceability. Joint Base San Antonio, spread across Lackland, Randolph and Fort Sam Houston, adds military facility and contract work.
The other big thread is steel. Trailer and truck body builders along I-35 and I-10 turn out flatbeds, livestock trailers and equipment haulers for ranches and oilfield crews. Fabrication and welding shops build skids, pipe racks and structures for Eagle Ford operators, plus the gates, carports and ranch jobs that fill the rest of the week.
Popular materials in San Antonio
Square and rectangular tube is the backbone of trailer frames and gates. A500 Grade B or C is the structural spec to call out. A513 is mechanical tubing, fine for lighter frames but not a swap when a drawing says A500. Carbon steel plate in A36 covers gussets, hitch plates and skid bases, and A572 Grade 50 steps in when an engineer wants more yield strength without going thicker.
Aluminum plate in 6061-T651 is the machining workhorse for aerospace tooling, with 7075 when the part carries real load. Structural shapes, mainly channel for trailer crossmembers plus angle and flat bar, round out most San Antonio orders.
