Collector Boxes

Collector boxes can be used in a roof drainage system where the building incorporates parapet walls and no internal drains.  A properly designed collector box and scupper can efficiently move water from the roof adding piece of mind to tenants and building owners.  Metal Panel Systems fabricates collector boxes from a line of standard sizes and gauges; however custom options are also available.

Collector boxes are manufactured with Pittsburgh seams when using 24-gauge steel.  Pittsburgh seams allow for a clean look with no exposed fasteners while providing added leak protection and structural durability.

Other material and gauges are available using riveted seams.   They include .040 Aluminum, .032 Aluminum and 16OZ Copper

Standard sizes include 12×12 (CB1212), 12×16 (CB1216), 12×24 (CB1224).

All Collector Boxes can be manufactured with pre-installed outlet tubes for a small fee.
