A Guide by 21 Rebar for Richmond, New Westminster, Burnaby, Port Coquitlam, Langley, Abbotsford, Surrey & Delta

Concrete is strong in compression but weak in tension. That’s where rebar, or reinforcing bar, comes in, specifically, deformed rebar. With ridges and lugs along its surface, deformed rebar is designed to bond better with concrete, enhancing structural integrity and reducing slippage. At 21 Rebar, we specialize in supplying high-quality deformed rebar across British Columbia, including major construction hubs such as Richmond, New Westminster, Burnaby, Port Coquitlam, Langley, Abbotsford, Surrey, and Delta.

Let’s take a closer look at the world of deformed rebar, exploring the types, sizes, and grades commonly used in today’s construction, as well as why it plays a critical role in the structural landscape of British Columbia.

What is Deformed Rebar?

Deformed rebar differs from plain rebar by its textured surface, ridges that provide greater mechanical anchoring with concrete. This ribbed design allows it to resist slippage under stress, improving the overall load-bearing capacity of structures.

Whether it’s a multi-storey residential building in Surrey, a commercial complex in Richmond, or public infrastructure in Abbotsford, deformed rebar is an essential component in modern construction.

Types of Deformed Rebar by Diameter

Rebar is classified by its diameter, and different types serve different purposes depending on structural demands. At 21 Rebar, we provide a range of deformed rebars suitable for residential, commercial, and industrial projects across BC.

30mm Deformed Rebar

This heavy-duty rebar is ideal for large-scale infrastructure projects such as bridges, retaining walls, and high-rise buildings. Its increased thickness offers enhanced tensile strength, making it a reliable option for areas experiencing heavy loads or dynamic forces, like high-traffic zones in Burnaby or New Westminster.

25mm Deformed Rebar

A popular choice for reinforced concrete beams and slabs, the 25mm deformed rebar strikes a balance between strength and workability. In growing urban centers like Langley and Delta, it is frequently used in commercial buildings and parking structures.

20mm Deformed Rebar

Used extensively in residential and low-rise construction projects, the 20mm variant provides adequate tensile strength for general structural applications, such as footings, slabs, and columns. It’s a go-to option for housing developments in Port Coquitlam and Abbotsford, where reliability and affordability matter.

Common Rebar Sizes: Flexibility in Construction

Beyond the heavy-duty bars, smaller diameters like 10mm and 15mm are widely used in fine detailing and specific structural zones that don’t require massive load-bearing capacity but still need tensile support.

10mm Rebar

This is often used for stirrups, ties, and minor reinforcement zones in slabs and beams. It’s extremely versatile and lightweight, making it ideal for reinforcement detailing in residential construction across Surrey and New Westminster.

15mm Rebar

Sitting between light and medium-duty applications, 15mm deformed rebar is perfect for slab reinforcement, floor systems, and wall panels. With a bit more strength than 10mm, it offers better support while maintaining flexibility and ease of placement.

Whether you’re reinforcing a small house in Langley or working on a mid-rise office space in Burnaby, 21 Rebar can supply the right size and quantity of rebar to meet your specifications.

Rebar Grades: Grade 400 vs Grade 500

Apart from size, grade plays a crucial role in determining the yield strength of the rebar, that is, how much stress it can withstand before permanently deforming.

Grade 400

With minimum yield strength of 400 MPa, Grade 400 rebar is sufficient for most structural applications. It’s commonly used in low to mid-rise buildings, sidewalks, pavements, and residential footings. If you’re working on general-purpose construction in areas like Delta or Abbotsford, Grade 400 is a cost-effective and reliable choice.

Grade 500

Offering yield strength of 500 MPa, Grade 500 deformed rebar is ideal for high-performance applications. From commercial towers in Richmond to transport infrastructure in New Westminster, this higher-grade rebar offers better stress resistance, reduced steel usage (due to its higher strength), and improved structural safety.

At 21 Rebar, we ensure that all grades we supply meet or exceed Canadian standards, giving engineers and contractors peace of mind on every project.

Why British Columbia Needs Quality Rebar

British Columbia’s construction industry is evolving rapidly, especially in growing urban regions like Surrey, Langley, and Burnaby. Earthquake-prone zones like the Lower Mainland require structures that can withstand seismic activity, and this means relying heavily on high-grade, high-strength rebar to absorb shocks and stresses.

With increased urban density and infrastructure investments, the demand for deformed rebar is not only growing but also becoming more sophisticated. That’s why 21 Rebar prioritizes consistency, durability, and fast delivery across all the key cities, from the industrial areas of Delta to the residential suburbs of Port Coquitlam.

What sets 21 Rebar apart is our focus on
