Absolutely! We encourage clients to visit the job site and stay involved. We'll schedule regular check-ins and provide progress updates throughout construction. For safety reasons, we ask that you coordinate visits with our site supervisor and follow all safety protocols while on-site. Many clients enjoy watching their building take shape!

Materials & Specifications

Red iron steel refers to hot-rolled structural steel that's oxide-coated (giving it a red appearance) and used for building frames. It's the industry standard for commercial and industrial buildings because of its superior strength and durability.

Benefits of red iron construction:

Stronger and more durable than pole barn construction
Allows for clear-span designs (no interior columns)
Engineered to meet local wind and snow loads
Fire-resistant and non-combustible
Lower insurance premiums than wood structures
Longer lifespan (50+ years with proper maintenance)

R-panels are exposed fastener metal panels with vertical ribs spaced 12 inches apart. They're our standard exterior panel system because they offer excellent weather protection, durability, and value.

R-panel advantages:

26-gauge or 29-gauge galvanized steel with protective coating
Excellent water runoff and weather resistance
Available in multiple colors to match your preference
Cost-effective compared to standing seam systems
Easy to repair and maintain
Proven performance in Texas weather conditions

Insulation is highly recommended for most applications, especially in Texas where summer heat is intense. We offer several insulation options:

Fiberglass blanket: R-10 to R-30 values, economical option
Spray foam: R-20+ values, best thermal performance and air sealing
Rigid board: R-8 to R-16 values, moisture resistant

Insulated buildings are more comfortable, have lower energy costs, prevent condensation, and can reduce HVAC equipment size. For warehouse and storage applications without climate control, insulation may be optional.

Extremely well! Metal buildings are engineered specifically for Texas conditions:

Heat: Metal roofs reflect sunlight and heat, reducing cooling costs. With proper insulation and ventilation, interiors stay comfortable.
Wind: Red iron frames are engineered to withstand high winds and meet local wind load requirements. All connections are bolted, not nailed.
Hail: Metal panels are more hail-resistant than traditional roofing. Minor dents don't affect structural integrity or leak protection.
Rain: R-panel systems shed water quickly and properly installed flashing prevents leaks.

We design every building to meet or exceed Texas building codes and local requirements.

Permits & Regulations

In most cases, yes. Building permits are required for commercial structures in nearly all Texas counties and municipalities. Requirements vary by:

Building size and use
Location (city limits vs. unincorporated county)
Zoning regulations
Property setback requirements

We handle the entire permitting process for you, including engineering stamps, site plans, and submittals. Our team knows local requirements throughout the San Antonio area and will ensure your project is fully compliant.

Every building includes professional engineering stamps from Texas-licensed structural engineers. We provide:

Structural calculations for wind and snow loads
Foundation design stamped by PE
Building frame engineering drawings
Anchor bolt plans
Connection details

These certifications are required for permits and ensure your building meets all safety standards and building codes.

Customization & Options

Absolutely! Every building we construct is custom-designed for your specific needs. Customization options include:

Size & Layout: Any dimensions, clear-span or with interior columns
Colors: Multiple colors for roof, walls, and trim
Doors: Overhead doors, walk doors, sliding doors in various sizes

We coordinate all trades (electrical, plumbing, HVAC) to deliver a turnkey workspace. Whether you need a simple office or a fully finished interior, we can handle it.

Maintenance & Warranty

Very little! Metal buildings are low-maintenance compared to traditional construction. Recommended maintenance includes:

Annual visual inspection of roof and walls
Check and tighten fasteners if needed
Clean gutters and downspouts
Touch up any scratched paint
Inspect door hardware and lubricate moving parts
Check weather seals around openings

With proper maintenance, a quality metal building will last 50+ years. Steel doesn't rot, warp, or attract termites like wood structures.

We stand behind our work with comprehensive warranty coverage:

Workmanship: 1-year warranty on all labor and installation
Structural Steel: 20-year manufacturer warranty
Metal Panels: 40-year paint warranty, 20-year perforation warranty
Foundation: Covered under our workmanship warranty

We also provide ongoing support after your building is complete. If you have questions or concerns, we're just a phone call away.

Modern metal buildings are designed to resist rust through multiple protective layers:

Galvanized steel coating (zinc layer)
Factory-applied paint finish
Rust-inhibiting primer

If surface scratches occur, they can be easily touched up with paint. Red iron structural steel is also treated to resist corrosion. In coastal areas or highly corrosive environments, we can upgrade to heavier galvanization or stainless steel fasteners for added protection.

With proper care, rust is rarely an issue with quality metal buildings.
