Knockthroughs and RSJ Installation

By removing internal walls, we can design interiors that create a natural flow throughout your home. Partition wall removal and knockthroughs are usually completed quickly. However, removing and realigning supporting walls is a more complex job requiring careful calculations and inserting rolled steel joists.

RSJs are more than just structural steel beams; they are the backbone of your home, providing strength and versatility. They distribute loads across their length, transferring weight and stress from a load-bearing structure to the foundation.

Their unique shapes maximise strength and minimise material usage, making RSJ installation work efficient, economical, and capable of supporting substantial loads while maintaining structural integrity.

  • Strength and Durability: RSJs are incredibly strong, supporting heavy loads without bending or breaking thanks to their steel composition
  • Ease of Installation: They can be prefabricated to specific sizes and shapes, simplifying construction and reducing labour and time
  • Cost-Effectiveness: Their strength results in lower overall maintenance, making them a cost-effective choice for structural alterations and renovations
  • Fire Resistance: Steel is inherently fire-resistant, and RSJs can be further treated or coated to enhance their fire protection properties, providing additional safety

Thanks to knockthroughs and RSJ installation, our builders at Balaam Ltd can create stunning interiors that promote spacious and more purposeful living conditions.

What is classed as a structural alteration?

Structural alterations include changes that affect the integrity or load-bearing parts of a building, such as removing walls, enlarging doorways, or adjusting roof structures. These changes often require building regulations approval and professional input.

Do I need a structural engineer for internal wall removal?

Yes. If the wall is load-bearing, a structural engineer must assess it and provide calculations for any required supports (such as steel beams). We work with trusted engineers to ensure all alterations are safe and fully compliant.
