Expanded Corner Beads: Durable, Easy to Install, Cost-Effective

Expanded Corner Beads are metal profiles used in construction to reinforce and protect the corners of walls and ceilings, particularly in plastering and drywall applications. They are typically made of galvanized steel or aluminum and come in various sizes and thicknesses.

Specifications and Sizes:

Thickness

• 0.2 mm to 0.5 mm: These thinner gauges are typically used for light-duty applications where minimal structural support is needed. They are ideal for interior decorative trims or areas that will not endure significant mechanical stress.
• 0.6 mm to 1.5 mm: This mid-range thickness is well-suited for general residential and commercial constructions, offering a good balance between flexibility and strength for standard wall corners and ceilings.
• 1.6 mm to 3 mm: The thickest options in the range provide maximum durability and are primarily used in industrial settings or in areas where the bead must withstand high impacts or heavy loads. This range is also preferable for external corners that are exposed to severe environmental conditions.

Custom thickness options are also available to meet unique project specifications, providing the flexibility needed to tailor materials precisely.

Length

• 1 Meter Length: This is the shortest option available, ideal for projects requiring precise, small-scale installations. It reduces waste and is particularly useful in settings where space is limited or where smaller, segmented installations are needed.
• 2 Meter Length: A versatile mid-range option that strikes a balance between coverage and manageability. This length is commonly used in standard room dimensions, providing a good fit for most internal and external corner installations without excessive splicing.
• 3 Meter Length: The longest standard length available, suitable for larger areas where continuous lengths can improve installation efficiency and aesthetics by minimizing joints.

For projects with specific length requirements that fall outside the standard sizes, custom length adaptations are available

Width

• 0.5 Inches Width: This is the narrower option available, commonly used where less coverage is sufficient, or in projects with tighter space constraints. It’s ideal for residential interiors where subtle corner reinforcement is required without overwhelming the design aesthetics.
• 0.625 Inches Width: Offering slightly more coverage, this width is preferred for commercial or industrial applications where a wider flange can provide better adhesion and increased durability.

To accommodate projects with unique specifications or unusual wall dimensions, custom widths can be manufactured.

Flange Size

• 20 × 20 mm: Ideal for smaller scale projects where precise angles are necessary but extensive coverage is not required.
• 25 × 25 mm and 30 × 30 mm: These mid-range sizes are versatile and commonly used in both residential and commercial construction for providing adequate mesh reinforcement while maintaining ease of installation.
• 35 × 35 mm and 45 × 45 mm: Suitable for larger construction projects that demand more robust reinforcement and greater surface area coverage to ensure structural integrity.
• 50 × 50 mm, 55 × 55 mm, and 60 × 60 mm: These are the largest flange sizes available and are typically used in industrial applications or in areas where the highest level of stability and support is required.

Features and benefits of expanded corner beads:

• Reinforcement: The expanded metal design provides excellent reinforcement, preventing cracks and damage to the corner.
• Protection: The metal bead protects the corner from impact and wear and tear.
• Straight Corners: The bead ensures straight, clean, and professional-looking corners.
• Easy Installation: The bead is easy to install using screws or nails.
• Durability: The metal construction is durable and long-lasting.  

Application for Expanded Corner Beads

Expanded Corner Beads are extensively utilized in the construction and interior decoration sectors, particularly designed to reinforce vulnerable areas such as wall corners, columns, and window edges. These areas are often susceptible to wear, impact, and damage. Whether applied in residential housing or commercial building projects, Expanded Corner Beads offer an excellent solution, ensuring durable edge protection while enhancing the visual appeal of the structure.
