1/2" Thick 22.5" x 4" D-Pipe Aluminum Welding Pad | Marine Grade 6061-T6
Part Number: 0152
Extra-Long D-Pipe Welding Pad for D3 Profile
1/2" thick marine-grade 6061-T6 aluminum welding pad engineered for D3 D-profile pipe installations requiring an extended 22.5" mounting surface. The extra-long footprint provides maximum load distribution and weld area for heavy-duty T-top and tower base connections. Pre-formed to conform to D3 pipe contours along the full 22.5" length. Standalone component — no paired backing plate required.

Common Applications
Heavy-duty T-top base mounts, tower leg foundations, large center console hard top supports, and structural offshore installations where a D3-profile pipe requires an extended welding surface for maximum strength and load distribution.
Frequently Asked Questions
Why is this pad 1/2" thick instead of 3/8"?
The 1/2" thickness provides additional structural support for the extended 22.5" length. The extra material prevents flexing under load and provides more weld volume at the pipe interface for heavy-duty structural connections.
What does a welding pad do?
A welding pad provides a precision-machined mounting surface that conforms to D-profile pipe contours. The pad distributes loads across a wider area than the pipe alone, preventing stress concentrations and fiberglass damage at mounting points.
What does D3 mean?
D3 refers to the D-profile pipe size this pad matches — a 3" wide D-shaped aluminum profile commonly used in T-top and tower construction.
Does this need a backing plate?
No. This is a standalone welding pad designed for direct installation without a paired backing plate. The 1/2" thickness and extended length provide sufficient structural support on their own.

Due to this item's size and weight we can only ship it in an economical way via Less Than Truckload (LTL) consolidated land shipping, and only to the contiguous 48 States.
For shipping inquiries to AK, HI, PR, US-VI, and international shipping, please contact us first at sales@weldingworldinc.com.
All of the destinations above we can only serve as a Free Carrier (or FCA) modality, that requires the customer to contract and pay for their carrier service of choice. We can still ship the item, but only to a warehouse/receiving office within the 48-contiguous States.
In plain terms what this means is that if you want to ship your product to any non-contiguous US territory or internationally, you, the customer, has to provide us with the warehouse address of the carrier that serves your locality with an address within the contiguous 48-US States, as we do not ship overseas on our own.
