Haag Metal Thickness Gauge for Roof Panels & Membranes HPMG

Estimate the thickness of steel and aluminum panels; as well as single-ply membranes with Haag’s Thickness Gauge for Panels and Membranes.

Unlike other gauges that only estimate uncoated steel panels, the Haag Panel and Membrane Gauge will help you suggest replacement panels on more roofing types, with more accuracy.

Sometimes it is difficult to determine if a panel is aluminum or steel - the Haag metal gauge features a rare earth BONUS Magnet that will help differentiate panel types.

If the panel is made of steel, the magnet will react.  If the panel is made of aluminum, the magnet will NOT react.  (Some stainless steels also are not magnetic and will not react.)

Haag Metal Thickness Gauge for Roof Panels and Membranes Measures:

Steel: Uncoated or coated, galvanized or Galvalume® (with or without additional coating)

Aluminum: Uncoated and anodized panels

Single-ply Membranes:  For all single-ply membranes (excluding modified bitumen, self-adhering, and fleece-backed)

EASY To Use...  Follow these easy steps to estimate:

1. Identify the type of material you are inspecting.  (Use the magnet to help you determine if you are looking at aluminum or steel.)

2. Start with the widest slot.  Holding the gauge loosely in one hand at a 30 degree angle to the material, drag the slot along the edge of the panel or membrane.  Note that the slightest burr (rough edge on the material after cut) will misrepresent thickness.  Do not force the gauge onto the material.

3. When dragging the tool, the slightest resistance constitutes refusal.  The slot prior to refusal is the estimated panel thickness.

4. Take multiple measurements to qualify your results.  Record all findings.
