Expanded-Metal Partition or Metal Lath Partition
Metal lath and plaster have been used in both residential and commercial applications to partition interior space and in non-load-bearing exterior walls where appearance and durability are key.
- Rib lath is widely used as a plaster backing on ceilings,walls and stud partitions.
- Rib Lath is also ideal for refurbishing damaged or aged masonry walls
- Material: Galvanized Steel for dry conditions.
- Stainless Steel for external use and condition of heavy condensation or persistent damp.
Expanded Metal Lath
Expanded Metal Lath has stiffening V ribs providing strength for its tenforce. This type of lath is stiffened by longitudinal ribs and gives a uniform coat depth for large areas. It serves as an excellent plaster base and also provides a high degree key to mechanical bonding with the plaster and the paint. It also serves as a high degree key of mechanical bonding with plaster or render.
It has widely been used as a background for plaster, render, stucco application in construction of suspended ceilings partition.
When conventional plasters like (cement+gypsum) used with expanded metal lath, they create a mechanical bond with the lath for maximum strength and durability.
Metal laths are fabricated from galvanized wire into a grid or hexagonal pattern and hence due to galvanization, corrosion is resisted.
- Plaster used in the construction of this partition wall must not only be strong but must also be crack resistant and economical to apply.
- Mixes prepared from Portland cement and some gypsum cements offer these qualities and is known as Gypsolite.
- Thickess: It varies from 19mm to 64mm.
- It is used where thinner walls are required.
- They are cost effective and light in weight and durable.
- They are used for inbuilt shelves and parapet walls.
First a framework of metal mesh is built.
After the initial step of constructing a framework of metal mesh, it is Plastered from both sides.
