MCLELLAN "B" STYLE TANK CONSTRUCTION

Example configuration — built to your spec.

1

Single Longitudinal Weld Seam

One seam down the length of the shell instead of several — every weld you remove is a seam that can’t leak or split.

2

Box Section Sub-Frame

A closed box section holds its shape under load, whereas an open "L" section twists and leaves the tank fighting the chassis — working the seams loose.

3

Dished & Flanged Heads & Baffles

Increased structural integrity and road safety — prevents accelerated fluid movement when braking.

A-Tank vs. B-Tank

Choose the A-Tank for McLellan’s flagship, heavy-duty configuration with added structural reinforcement. For operations focused on essential performance and value, the B-Tank offers a leaner, cost-efficient build without compromising McLellan quality.
