<p data-start="295" data-end="681">Even in 2025, with so much awareness and information available, many home builders and contractors continue to repeat the <strong data-start="417" data-end="453">same material-selection mistakes that lead to structural issues, safety risks, and higher long-term costs. These mistakes vary from region to region, but the impact is often the same &mdash; poor durability, faster corrosion, weak foundations, and expensive repairs.

<p data-start="683" data-end="724">Some of the most common mistakes include:

<ul data-start="726" data-end="1155">
<li data-start="726" data-end="780">
<p data-start="728" data-end="780">Choosing low-grade or uncertified steel bars (TMT)

</li>
<li data-start="781" data-end="849">
<p data-start="783" data-end="849">Using cheap or non-coated fasteners in humid or coastal climates

</li>
<li data-start="850" data-end="929">
<p data-start="852" data-end="929">Selecting welding rods that don&rsquo;t match the project&rsquo;s strength requirements

</li>
<li data-start="930" data-end="995">
<p data-start="932" data-end="995">Ignoring proper curing materials and waterproofing essentials

</li>
<li data-start="996" data-end="1076">
<p data-start="998" data-end="1076">Opting for the lowest-priced materials instead of checking quality standards

</li>
<li data-start="1077" data-end="1155">
<p data-start="1079" data-end="1155">Poor on-site storage that leads to rust, moisture damage, or contamination
