How Can I Tell If My Angle Iron Is Rusting?

How Can I Tell If My Angle Iron Is Rusting?

Hello from Maçonnerie Montréal, your go-to masonry service provider in Montreal, Laval, Longueuil, South Shore, and North Shore. As industry professionals, we often field questions related to the various aspects of masonry, one of which is, "How can I tell if my angle iron is rusting?" This guide aims to shed light on this subject, helping you identify the signs of rust on angle irons in your masonry structure.

Understanding Angle Irons in Masonry

Angle irons are L-shaped iron or steel pieces that play an essential role in masonry structures, providing critical support and reinforcement. When left unchecked, rust can compromise the strength and durability of these angle irons, potentially jeopardizing the structural integrity of the entire building. Thus, early detection of rust on angle irons is crucial.

Identifying Rust on Angle Irons: What to Look For?

Recognizing the signs of rust on angle irons can save you from costly repairs or replacements in the future. Here are some symptoms to watch out for:

  1. Visible Rust: The most apparent sign is the sight of rust itself. This can appear as red, orange, or brown discoloration on the surface of the angle iron. Rust may also present as flaking, chipping, or pitting of the metal.
  2. Weakness in Structure: If you notice any sagging, bending, or instability in your masonry structure, this could indicate rusting of internal angle irons.
  3. Cracks in Masonry: Rust can cause the angle iron to expand, leading to cracks in the surrounding masonry. If you notice unusual cracking patterns, especially around where angle irons are installed, it could be a sign of rust damage.
  4. Water Damage or Dampness: Rust thrives in moist conditions. If a certain area in your building has been exposed to water damage or persistent dampness, there's a high chance that the angle irons in that area could be rusting.

What To Do When You Detect Rust?

If you spot any signs of rust on your angle irons, immediate action is necessary. Depending on the severity of the rust, you might be able to treat the affected area with rust converter and protective paint. However, for extensive rust damage, angle iron replacement might be necessary. In such situations, we recommend hiring a professional masonry service provider like Maçonnerie Montréal.
