5 Common Metal Stair & Railing Repair Issues — And How to Fix Them
Metal stairs and railings are the backbone of safety and design in any building — whether it’s a residential porch, apartment complex, or industrial facility. But constant exposure to Atlanta’s humidity, rain, and temperature swings can take a toll. Over time, even the strongest metal structures begin to rust, loosen, or crack.
If you’ve noticed your stairs squeaking, your handrail wobbling, or rust creeping along the surface — you’re not alone.
At ATL Welding, we specialize in on-site metal repair and restoration, helping homeowners, contractors, and property managers keep their metalwork safe, strong, and looking brand new.Rust and Corrosion — The Silent Destroyer
Atlanta’s humid weather and outdoor exposure make metal stairs and railings especially vulnerable to rust. Over time, oxidation weakens the metal, causing flaking, pitting, or complete section loss.
How to Fix It:
- • Use a wire brush or grinder to remove surface rust.
- • Apply a rust converter to stop corrosion in deeper areas.
- • Prime with a zinc-rich metal primer and finish with a protective paint or powder coat.
- • For severe cases, replace damaged sections and re-weld for full strength.
Loose or Wobbly Railings
Repeated use, vibration, and time can loosen bolts, welds, or joints — especially where railings meet stairs or floors. This can be a major safety hazard if left unattended.
How to Fix It:
- • Inspect the base plates and weld joints for cracks or movement.
- • Re-tighten anchor bolts or replace corroded hardware.
- • When welds have failed, grind and re-weld the affected sections for long-term reinforcement.
Cracked Welds or Broken Joints
Cracks in welds are often caused by stress, impact, or poor initial workmanship. Left untreated, they can spread quickly, leading to complete structural failure.
How to Fix It:
- • Identify the crack area and grind out the old weld.
- • Clean the metal surfaces thoroughly.
- • Re-weld using the correct technique (MIG, TIG, or Stick, depending on material).
- • Inspect for alignment before cooling.
Misaligned or Warped Components
Heat, pressure, or improper installation can cause metal pieces to bend, twist, or misalign. This not only looks bad but can cause uneven weight distribution and early fatigue.
How to Fix It:
- • Use controlled heat and precision tools to straighten sections.
- • Re-secure joints and re-weld connections.
- • Check level and symmetry across the entire structure.
Paint Peeling & Surface Deterioration
Over time, UV rays and weather strip away the protective coatings on metal stairs and rails, leaving them exposed to rust and discoloration.
How to Fix It:
- • Remove loose paint using a grinder or sandblaster.
- • Clean thoroughly before applying a new primer.
- • Re-coat with high-quality epoxy or powder finish to protect against moisture and heat.
