Galvanized Metal Post Caps – Weatherproof Protection in Black & Silver

Why Choose Galvanized Metal Post Caps

BarrierBoss galvanized metal post caps shield fence and deck posts from rain, snow, freeze-thaw, and UV damage, preventing cracking, rot, and decay. Available in sleek black or silver dip-coated finishes, these corrosion-resistant steel caps provide long-term protection and a polished, professional look for Canadian homes and properties.

Pro Tip: Apply a thin bead of exterior-grade silicone under each cap before sliding on for an extra-tight seal against moisture—especially important in Canada's freeze-thaw cycles and heavy snow regions.

Built to Withstand Canada's Harshest Conditions

Our galvanized metal post caps are crafted from high-grade galvanized steel with a durable black or silver dip-coated finish for superior rust and corrosion resistance. Designed to protect wood and metal posts from water infiltration, splitting, and weathering, these caps lock in strength and style for years—even in heavy snow, salt exposure, high winds, and extreme temperature swings.

Available in multiple sizes to fit standard 4x4 and 6x6 posts (true dimensions), they slide on easily and can be secured with screws for maximum hold in high-wind areas. The sleek matte finish adds a modern, finished touch to fences, decks, pergolas, and outdoor structures while eliminating the need for ongoing maintenance.

Perfect for residential yards, rural acreage, or commercial fencing across Canada, these caps provide reliable, long-term defense and elevate your property's curb appeal without the hassle of painting or sealing.

Did You Know? The black and silver dip-coated finishes are UV-stabilized and colour-fast with a 30-year no-fade guarantee—ensuring your post caps stay sharp and protected through Canada's sun, snow, and salt exposure.

Outstanding product and customer service

The wire use for this fencing is thick and sturdy. Also, the fencing material is well coated to stand up to the elements. Not only is the fencing material well made, but the support you get from the customer service department is outstanding. They promptly answer emails, and they keep you informed about the delivery. Barrier Boss is an outstanding company!

We would recommend Barrier Boss

Barrier Boss products are well made. Our initial order for 3 x standard panels took forever (as they warned us) but when we ordered the remaining custom panels, it was super quick. It was great to deal with Leo. I liked thst they bring their pets to work :-)

A Great Hogwire Fence Option

We have been looking at installing a hog wire fence and found these pre-built panels from BarrierBoss. They made short work of building our fence and we were thrilled with the quality of the product and the delivery cost. Other than a delay caused by the tariffs we couldn't be more pleased.
