Most manufacturers ship components with a “shop coat,” a temporary protective layer applied to all surfaces. This coating helps reduce the impact of normal atmospheric exposure, but it is not intended to provide complete protection during harsh winter conditions.
The Winter Challenge: Road Salt and Deicers
Transporting building materials in winter often means exposure to salt and chemical deicers used on roadways. These materials can splash onto steel components during transit, especially when shipped on open flatbed trucks. Once salt or deicers reach the surface, they can break down the shop coat and accelerate corrosion.
A Simple Solution: Use Tarps During Transit
To reduce risk, request that your shipment be covered with a weatherproof tarp. This small step can make a big difference in protecting your investment. If you are arranging your own pickup, make sure the tarp is made of a durable, weather-resistant material and is securely fastened. Avoid leaving gaps or holes that could allow water, snow, or ice to collect, as freeze-thaw cycles can compromise the primer and lead to early surface damage.
On-Site Storage Best Practices
Winter precautions should also extend to the job site. Whenever possible, unload steel components directly into position for erection. If temporary storage is necessary, place materials above any damp surface—either on a ground tarp or a clean concrete slab—and cover the stack to prevent moisture buildup. Ensure the area is elevated enough so that melting snow or site runoff cannot flow beneath the covering and reach the metal.
