RECTANGULAR MESH

What is rectangular reinforcing mesh?

Rectangular mesh is a prefabricated welded reinforcement product manufactured from high-strength D500L ribbed steel wire. Unlike square mesh, which distributes reinforcement evenly in both directions, rectangular reinforcing mesh is designed with closer longitudinal wire spacing to provide greater reinforcement along the primary load direction.

This allows engineers to efficiently reinforce concrete elements that experience higher tensile forces in one direction than the other. At Bestbar, we supply a comprehensive range of RL-grade products to meet the requirements of residential, commercial and civil construction projects throughout Australia.

When should you use rectangular mesh?

Rectangular reinforcing mesh is specified when a concrete element requires greater reinforcement in one direction than the other. By concentrating more steel along the primary load path, rectangular mesh provides an efficient reinforcement solution without unnecessarily increasing steel content across the entire slab or wall.

Structural engineers commonly specify rectangular steel mesh for:

• One-way spanning suspended slabs
• Long warehouse bays and industrial floor slabs
• Concrete walls requiring directional reinforcement
• Tilt-up concrete panels
• Precast concrete elements
• Loading docks, ramps and accessways
• Commercial and civil projects where RL grades are specified in the engineering drawings

Because every project has different structural requirements, reinforcement should always be installed in accordance with the engineer’s documentation. If you’re unsure which mesh rectangle best suits your project, our experienced team can assist with product selection and scheduling.

Rectangular mesh sizes and specifications

Bestbar supplies a complete range of RL-grade reinforcing mesh to suit projects of varying sizes and structural requirements. Each grade is manufactured with specific longitudinal and cross-wire diameters and spacing configurations, allowing engineers to select the most appropriate reinforcement for the design loads.

Our range includes:

• RL718
• RL818
• RL918
• RL1018
• RL1118
• RL1218

As the RL grade increases, the longitudinal wire diameter and overall steel content also increase, providing greater reinforcement capacity for more demanding structural applications.

While RL818 and RL918 are commonly specified for many residential and light commercial projects, heavier grades such as RL1118 and RL1218 are often selected for larger commercial and civil works. Final mesh selection should always follow the engineer’s structural drawings and specifications.

Estimating how much rectangular mesh you need

Ordering the correct quantity of reinforcement helps reduce unnecessary delays, minimise waste and keep projects running efficiently.

As a general guide, calculate the total slab area by multiplying the length by the width. This provides the total area to be reinforced. You can then estimate the number of sheets required based on the coverage of each sheet, while allowing additional material for laps, cuts and site-specific requirements.

Keep in mind that actual quantities will vary depending on factors such as:

• Required lap lengths
• Slab geometry
• Openings and penetrations
• Reinforcement layout
• Engineer specifications

If you’d like greater certainty before ordering, our estimating team can calculate reinforcement quantities directly from your engineering drawings, helping ensure you order the right amount of rectangular mesh for your project.

Complete your reinforcement package

Many construction projects require more than one type of reinforcing mesh to meet structural requirements. While rectangular mesh is commonly specified for slabs and structural elements requiring greater reinforcement in one direction, other mesh products may also be required, depending on your engineering drawings.

Explore our selection of trench mesh, galvanised mesh and square mesh to support footings, slabs and specialised corrosion-resistant applications. By sourcing your reinforcing mesh from Bestbar, you can simplify procurement, coordinate deliveries and ensure all reinforcement products are manufactured to Australian Standards and backed by expert estimating and scheduling support.
