Building Features

Standard Features of Our Steel Buildings
Superior material and quality makes us stand out above the crowd.

At WonderSpan, we are dedicated to providing exceptional quality and value in every arch-style steel building we manufacture. Our commitment to strength, durability, and precision engineering is reflected in the following standard features and industry-leading warranties:

Panel Overlap

Smooth Panel Ends – Last 9 inches are flat with no crimps for a seamless fit
Precision Fit Design – Panels lock together securely for added strength
Faster Assembly – Reduces erection time by 30-40%, saving labor costs
Hassle-Free Installation – No struggling with alignment or adjustments
No Caulking Needed – Designed for a tight, secure seal without extra sealing
Competitor Panels Slow Installation – Crimped ends require drift pins for alignment, adding 30-40% more construction time and needing four rows of caulking for waterproofing

Panel Crimping

Tighter, Shallower Crimps – Designed for a stronger, more secure panel connection
No Buckling Issues – Precision engineering ensures a stable, durable structure
25% Stronger Panels – Enhanced design improves load capacity and resilience
Competitor Panels Weaken Over Time – Wider, deeper crimps cause buckling and reduced strength

Fasteners

Superior Corrosion Protection – 1000-hour salt spray test with JS Clear Coat for 5x more rust resistance
Optional High-Strength Bolts – Grade 8.2 bolts tested for 1500-hour salt spray durability
Built for Longevity – Designed for maximum durability and performance
Engineered for Strength – High-tensile fasteners ensure secure, long-lasting connections
Competitors Use Inferior Fasteners – Standard zinc bolts with no JS Clear Coat and no corrosion testing

Specifications

Precision-Gauged Steel – Available in 23 to 14 gauge, engineered for wind and snow loads
Premium Material Standards – AZ55 Galvalume® coating ensures high corrosion resistance and 40+ year panel life
Industry-Leading Warranty – Backed by a 40-year rust-through perforation warranty
Certified for Extreme Conditions – Florida-approved for high-velocity winds up to 150 mph
Competitors Use Lower Standards – Thinner materials, weaker coatings, and no Florida approval—resulting in shorter lifespans and only a 20-year warranty

Arch Material

40-Year Galvalume® Protection – Backed by a limited 40-year warranty for long-lasting durability
High-Strength Steel – Manufactured to ASTM standards with a minimum yield of 55 ksi for superior performance
Engineered for Structural Integrity – ASCE-compliant design ensures resilience against wind and snow loads
Stronger Panel Connections – 9” overlap with two rows of bolts, creating a 16-gauge beam equivalent at seams
Competitors Use Weaker Materials – Lower yield strength, no ASTM/ASCE compliance, and weaker 7” overlaps with only one row of bolts

Endwall Panels

Premium AZ55 Galvalume® Coating – 55% aluminum, 43.5% zinc, 1.5% silicone for maximum corrosion resistance
Deep Corrugation for Strength – 3.5” corrugation depth enhances durability and wind resistance
Industry-Leading Warranty – Backed by a 40-year limited rust-through perforation warranty
Certified for Extreme Weather – Florida-approved for high-velocity winds up to 150 mph
Competitors Use Weaker Panels – AZ50 coating, lower corrosion resistance, only a 20-year warranty, and no Florida approval

Panel Manufacturing

Proudly American-Made – Manufactured in the USA by American workers, ensuring top-tier quality
Industry-Leading Expertise – Backed by 42+ years of leadership experience in steel building manufacturing
Strict U.S. Compliance – Fully adheres to all state and federal laws for safety and reliability
Largest Arch Building Manufacturer – Unmatched production capacity with a reputation for excellence
Competitors Lack U.S. Standards – Some manufacture outside the USA, leading to weaker warranties and foreign legal restrictions.
