3-1/2" Flat Round Pre-Galvanized Steel Fence Post Cap

3-1/2" Flat Round Pre-Galvanized Steel Fence Post Cap

This 3-1/2 inch flat round pre-galvanized steel fence post cap is an intermediate-size pressed cover for measured round posts in commercial fence, gate, terminal, and perimeter applications. Its shallow top keeps the profile visually restrained. Correct procurement depends on separating this size from nearby three-inch and four-inch caps and documenting the actual post outside diameter.

Survey Intermediate Post Sizes Across the Fence Run

Begin at gates, ends, corners, and changes in fence type, then sample intermediate posts. Record actual outside diameter, roundness, seam, wall condition, top cut, and coating. A property may contain several repair generations even when the posts appear consistent from a distance. Create a marked schedule that assigns the 3-1/2 inch cap only to posts that have been measured or approved by sample.

Check the Pressed Rim Against the Post Top

The underside rim shown in the product images is part of the fit, so overall top width alone is not enough. Confirm internal cap clearance, rim depth, corner-free seating, and the amount of post engagement required by the project detail. Remove burrs only under an approved field procedure. If the post is filled, wired, or fitted with internal hardware, show that condition in the RFQ.

Choose the Corrosion-Protection Route Deliberately

Pre-galvanized material, post-fabrication hot-dip galvanizing, and powder coating produce different edge coverage, appearance, thickness, and fit allowance. Select one route rather than listing them as interchangeable. For powder-coated orders, provide color and gloss. For metallic finishes, state the exposure and acceptance standard. Any attachment that breaks the coating needs a defined repair method.

Keep Replacement Lots Traceable

Group the caps by property, fence run, phase, or installer where practical. Mark cartons with the 3-1/2 inch size, SKU, finish, quantity, and purchase-order reference. Avoid mixing loose caps with nearby sizes in an unmarked pallet box. On receipt, inspect representative pieces for diameter, pressed shape, rim consistency, finish, nesting marks, and carton count before approving the lot.
