Colorado is hard on outdoor structures. At 5,000+ feet, UV radiation is 25% more intense than at sea level. Wind gusts along the Front Range regularly exceed 100 mph. Winter snow loads can reach 3 feet or more in a single storm. And freeze-thaw cycling puts structural stress on joints and fasteners year-round.
Pre-fabricated aluminum pergola kits are designed for mild climates with gentle weather. They flex, rattle, and often fail catastrophically in Colorado's conditions. Wood pergolas look great for a few seasons before cracking, graying, and rotting.
A custom steel pergola from Oak & Iron is engineered for the actual conditions of your site. We design the structure, size the steel members to carry actual snow and wind loads, and fabricate it to last for decades — not a few seasons.
