We use ASTM A36 structural steel for stringers and platforms, hot-dip galvanized or powder-coated grating for treads, and stainless or galvanized hardware for every connection. Every material is documented with mill reports and traceable to batch through our material supply program, which matters for permitted work and insurance documentation. We also match paint finishes and detailing to suit the architectural style of your specific building, whether modern, mid-century, or traditional.

Chicago requires qualified exterior wall and appurtenance inspections annually for buildings taller than four stories under the Exterior Wall Maintenance Ordinance. For smaller walk-ups and mid-rise buildings, we recommend a qualified visual inspection every 12 to 24 months, plus a full hands-on structural inspection every five years. We also coordinate coating inspections with our metal stairs painting crew when a building needs both services scheduled together.

Yes, and it happens regularly across the neighborhood, especially on buildings converted to new uses or venues adding occupied upper floors. We handle permitting, structural analysis of the host wall, and any required reinforcement through our in-house steel fabrication shop. For additional guidance and project insights, visit our blog.

Repair targets specific failure points such as a cracked stringer, a failed anchor, or corroded treads, while preserving the bulk of the existing structure. Replacement removes and re-installs the entire system. When repair costs exceed roughly 50% of replacement, we recommend replacement because you reset the compliance clock, secure a fresh warranty period, and get the strength and durability of a brand-new engineered system.
