G model arch steel building

G-Model Metal Garage
Quality, durability, and economy are the hallmarks of the G-Model. Virtually maintenance-free and offering the maximum usable interior space with no obstructions, the G-Model is the perfect steel structure for storing industrial equipment, truck garages, storing hay, machinery, or equipment and still have room left over for a workshop. Manufactured in the U.S.A., these arch-style steel structures are many times stronger than I-beam buildings or the older-style pole-buildings, and are completely vermin-proof.


Ranging from 16 to 40 feet wide, and with no limit in length, the G Model is among the most versatile buildings offered, ideal for use as industrial shops, warehousing, retail storefronts, residential housing and RV storage. This model combines an attractive 4/12 roof pitch with a gambrel style wall design and makes a great hunting lodge or cabin. The G-Model is especially economical due to the factory’s efficient manufacturing process and its unique design strength in heavy snow and wind conditions.

G Series BuildingThe G-Model is manufactured of the same incredible Galvalume™ coated steel as our other models. Galvalume™ is the finest American prime-grade steel available, and is 7 times more rust-resistant than regular galvanized steel. G-Model steel structures are all backed by our Industry leading 40-year guarantee, the best warranty in the business. This building is virtually maintenance free so you can focus your time on business or hobby activities instead of repairs.
