Met-Seam Ltd ZinFlex

We are the sole distributors in the UK and Ireland of ZinFlex.

ZinFlex is a Soft Zinc which can be used as a real alternative to lead. It can be fixed using Hall Clips and pointed with sealant or mortar.

Zinflex has a bright shinny surface but will tone down after a couple of weeks and will form its own protective patina coating over time. It comes in coils 1.10m wide x 0.6mm or 0.7mm thick and we can split the width into any multiple of 1.10m wide.

It is pliable enough to be dressed over tile profiles and be used for flashings and soakers.

ZinFlex weighs only 5kg per m² compared to 20kg per m² for code 4 lead, which makes it more user friendly, easier to transport, easier to handle and has less structural pressures.

ZinFlex is environmentally-friendly in its extraction and production and it is also 100% recyclable.

ZinFlex can be used in all applications traditionally associated with lead; including canopies, dormer windows, bay windows, gutters etc. but it cannot be laid flat, ZinFlex must have a minimum fall of 3 degrees.

ZinFlex conforms to BSEN: 1179 : 95 Z1

ZinFlex can be easily cut and shaped with a pair of snips and formed with the usual plumber’s or roofing contractor’s tools, by hand or by machine. It can be welted and is easy to solder with Tinman's solder.

ZinFlex has no run-off staining and therefore unlike lead does not require an application of patination oil.

ZinFlex is suitable for new build and renovation work it can be used on ecclesiastical and historic buildings for renovations and repairs. It is ideal for replacement of damaged or stolen lead flashings, it is cheaper than lead and has a much less scrape value.
