TrussMetal is a metal fabrication shop in North Vancouver that works across Metro Vancouver. This page is for facility and maintenance managers, mechanical contractors, plant engineers and workshop owners.
We fabricate and supply the pan, its supports and any outlet. A drip pan catches leaks and drips so they can be seen and cleaned up. Secondary containment that a regulation, permit or engineer requires is a different job: we build it only to a specification the project supplies, and we don’t decide whether it complies.
Configurations
Under-equipment drip pans
Lipped pans with welded corners under pumps, compressors, gearboxes, hydraulic units and other equipment, sized to its footprint and drip points.
Pans with an outlet
A bottom sloped to a welded coupling where the plumber connects a drain line.
Pans with a grating
A removable grating or bearers so equipment or containers stand above what drips.
Pans for stands and frames
Built into an equipment stand or frame, or sized to sit under one.

Concept drawing
Concept drawings, illustrative only: not a tested design, a shop drawing or an installation detail, and not a photograph or record of completed TrussMetal work. Dashed parts are by others or bought in. Parts marked “if specified” are included only where the agreed design calls for them.
Liquid and Material
The liquid first
Tell us what the liquid is, its concentration and temperature, and how the pan is exposed to it: drips, splashes or standing liquid. Send its safety data sheet too. The data sheet identifies the liquid and its hazards; on its own it doesn’t show that a material, coating, weld or seal is compatible.
Material
Stainless steel (304 or 316), hot-dip galvanized or coated steel, or aluminum. For anything other than water or condensate, compatibility of the material, welds, any coating and any outlet seal with that liquid, at that concentration and temperature, is confirmed before we build, from applicable technical data or by your engineer or chemical supplier. We don’t claim chemical resistance.
Leak check
Welded seams are leak-checked before delivery by a method agreed for the order.
Supports, Handling and Emptying
Size and depth
Footprint, lip height and depth come from the equipment, the space and how much you want the pan to hold between emptying, as you set it.
Supports
On the floor on feet or pads, on a stand, or under a frame, and stiffened so it doesn’t flex when full.
Handling
Lifting handles or forklift pockets where a pan has to be moved to empty it.
Emptying
Through an outlet to a drain line, by pump or vacuum, or by lifting out where the pan is small enough. The plumber connects any drain line.
Required Containment
To a project specification
Where a regulation, permit, insurer or engineer requires secondary containment, the project supplies the requirement: the dimensions or capacity, the material, the joints, any outlet or valve, and the acceptance checks. We fabricate to that specification.
No assumed compliance
A custom pan doesn’t meet a containment requirement just because it is a pan. Whether it does is for the project’s designer or the authority to confirm; we don’t size containment, decide which rules apply or certify compliance.
The equipment and where it drips; the liquid, its concentration, temperature and exposure; confirmation that the material, welds, coating and seals suit it; size and depth, supports, outlet and handling; and for required containment, the project’s specification and acceptance checks.
Checked before delivery
Welded seams are leak-checked by the agreed method, and the outlet and grating are fitted.
Who Does What
Responsibilities that affect the quote
TrussMetal: the pan, supports, grating and outlet coupling, and the leak check. Supply only.
Owner, engineer or chemical supplier: the liquid’s details and the compatibility confirmation, any containment specification and acceptance checks, and compliance.
Plumber or installer: any drain connection, and placing and fixing the pan.
