Blockwork & Plastering

Blockwork & Plastering Accessories

Introduction

In this section, KarZah provides its customers with an explanation of types and uses of two of the important blockwork accessories: Block Ladders and Corrugated Angels. We also include the description of major plaster accessories: Metal Lath, Angel Beads, Plaster Stop Beads, Plaster Architrave Beads, Plaster Movement Beads, Plaster Control Joint Beads and High-Rib Lath.

We need to use metallic building accessories in construction to cope with changes in weather and other natural conditions. Changes in temperature, humidity, winds and in some areas, earthquakes have adverse effect on building age. On the other hand, using plastering accessories allow us support and strengthen cement plaster where different building elements meet. This increases plaster cohesion and prevents cracks forming in building plaster.

2. Block Angles/Corrugated Angles
  • Manufacturers make block angles and other block wall ties from galvanized sheets, stainless steel sheets, or even from round steel rods.
  • Block angles are steel angles whose angle is straight. to increase friction.
  • Sometimes these ties come a fishtail on one side and holes on the other.
  • They connect block walls to concrete columns or to steel beams or connect block walls to concrete walls. This results in increasing stability of connecting building elements.

Plastering Accessories

Plastering accessories are made of galvanized steel coils, which can come in various thicknesses. These coils are cut into sheets of standard lengths. Straight slit-cuts of certain lengths are then made in these plates with specific vertical and horizontal and spacing in between them. In the last stage, the plates are stretched from both ends to form spaces in the form of a metal mesh, whose holes having rhombus shape.

Plastering accessories are fixed using steel nails of approximately 3 cm long with a galvanized or stainless-steel washer. During installation, the mesh part of the plastering accessory must be completely stretched. The mesh is fixed every 20 to 25 cm. The installer should distribute the mesh evenly over the space between the different building elements in both directions. Finally, apply a good layer of cement mixture over the mesh and ensure that there are no voids behind the mesh.

We recommend using a drill machine or a nail gun when installing the mesh part and not to use a hammer. The mesh, the washer, and the nail shall be of galvanized metal or stainless steel.

7. High Rib Lath

We use this type of plastering accessories to reinforce plastering work on ceilings, walls and floors as well. When the back surface is not supported by a whole

 

structure, high rib laths can work very well as a fake

plaster surface.

 

High rib laths are used also to reinforce raft slab foundations walls, I-beams, low straight bridges or bent bridges. Additionally, they are used as a separation between two huge concrete slab foundations, constructed at different time interval.
