Ordering made-to-measure flashing
Can PMX match an existing flashing profile?
Yes. Enter up to six leg dimensions and bend angles in the online designer. For complex parts, save the configuration and include a field sketch for fabrication review.
Which metals are available?
Typical options include galvanized steel, Galvalume, aluminum, stainless steel, copper and pre-finished steel. Available gauges and maximum lengths depend on the selected material and shop capability.
What is developed width?
Developed width is the flat sheet width required before bending. PMX calculates it from the profile legs and uses it to check material and press-brake feasibility.
Do you make chimney caps and roof curbs?
Yes. PMX designs and fabricates custom chimney caps, chase covers, roof curbs and rooftop equipment support rails in addition to linear flashing profiles.
