Gutter Guard Micro-Mesh in 316L Stainless Steel (AISI 316L (1.4404)) is used for keeping leaves, pine needles and debris out of rain gutters while letting water pass through a stainless micro-mesh on an aluminum frame. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.

Where 316L Stainless Steel Gutter Guard Micro-Mesh Is Used
- Roofing contractors: gutter protection upsells on re-roof jobs.
- Homeowners in wooded areas: stopping pine needles and seed pods.
- Wildfire-zone retrofits: ember-resistant gutters per local codes.
- Commercial buildings: low-maintenance gutters on tall structures.
Ordering Gutter Guard Micro-Mesh in 316L Stainless Steel
- Gutter width: Profile must suit 5 in or 6 in K-style gutters.
- Micro-mesh: SS316 woven micro-mesh stops pine needles; perforated aluminum alone suits large leaves only.
- Pitch: Install with a slight downward slope so debris slides off.
Mistakes to Avoid with Gutter Guard Micro-Mesh
- Choosing perforated-only guards under pine trees.
- Flat installation that lets debris mat on top.
