Whether you're designing a commercial warehouse, steel workshop, agricultural barn, or metal garage, you'll have total control over every aspect, including colors and roof type.
Our metal buildings are made to be flexible, versatile, and long-lasting, so they will not only meet but beyond your expectations. Examine the many personalized options we provide to make your structure uniquely yours.
One of the biggest advantages of working with San Marcos Metal Building is our industry-leading lead times. We understand that time is money, so we work hard to deliver your custom steel building kit on time, with all materials pre-numbered and ready for a fast, efficient assembly. Whether you’re building a backyard shop or a 100-ft warehouse, you can count on us for quick turnaround and quality workmanship.
Your metal building in San Marcos doesn’t have to look plain or industrial—unless that’s exactly what you’re going for. We offer a wide selection of color options so you can personalize everything from the wall paneling and roofing system to the trim, fascia, and wainscoting accents. Choose from modern, rustic, or traditional color palettes to create a look that fits your style. Whether you want your workshop to match your home, ranch, or business aesthetic, we make it easy to design a building that feels uniquely yours.
The paneling on your metal structure plays a major role in both its appearance and long-term durability. That’s why we offer multiple paneling styles to match your project needs. Horizontal panels provide clean, streamlined lines and allow for quicker installation—making them a smart choice for budget-conscious builds. For those seeking a more refined, high-performance finish, vertical panels offer superior water drainage, added structural strength, and a sleek, professional look—ideal for workshops, barns, and commercial buildings. Each panel type is engineered to handle San Marcos weather, with built-in wind resistance, effective rain runoff, and lasting curb appeal.
Every great metal building needs the right access points, and we offer a wide variety of doors and windows to enhance both functionality and ventilation. From roll-up garage doors designed for RVs, tractors, and heavy equipment, to insulated walk-in doors with added security features, we tailor each option to fit your needs. Framed window cutouts allow for ample natural light, while custom door framing gives you the flexibility to install your own specialty doors. Whether you need oversized barn doors for livestock or wide bay access for commercial operations, we’ll build every entry point to your exact specifications.
Your roof is your building’s first line of defense against the Texas elements, which is why we offer three durable roofing systems engineered for performance in San Marcos' climate. The Regular Roof features rounded edges and is a cost-effective option suited for areas with mild weather. The A-Frame Roof offers a classic gable style that handles moderate rain and wind with ease. For maximum durability, the Vertical Roof includes vertically aligned panels that allow for superior water runoff, making it ideal for heavy storms, falling debris, and high winds. Whether you're building a hay shed, auto shop, or backyard metal barn, we’ll help you select the right roof system for long-lasting protection and improved energy efficiency.
When it comes to metal buildings in San Marcos, we don’t just deliver a product—we deliver lasting value. While anyone can sell a basic steel shed, building something that stands the test of time takes expertise, precision, and local know-how. Here’s what sets San Marcos Metal Building apart from the competition:
