Timber Joist Hangers

Timber Joist Hangers

Timber joist hangers are metal brackets designed to support timber joists when fixing timber to timber in structural construction. They create a secure mechanical connection between the joist and the supporting beam, ledger board or wall plate.

Joist hangers are widely used in structural timber work including floor construction, loft conversions, decking frames and stairwell trimming. By supporting the joist from below, they allow installers to create strong structural connections without cutting complex timber joints.

Manufactured from pre-galvanised steel, Timco timber hangers provide good corrosion resistance and are suitable for most structural timber applications. In environments where additional corrosion protection is required, stainless steel hangers may be used.

Timco timber hangers conform to Eurocode 5 and are designed to provide reliable structural performance when correctly installed.

What is a Timber Joist Hanger?

A timber joist hanger is a metal bracket used to support timber joists when connecting them to another timber member such as a beam, ledger board or wall plate.

The hanger transfers the load from the joist into the supporting structure, helping create a stable and secure timber frame. Joist hangers are commonly used instead of traditional timber joints because they are faster to install and provide consistent structural support.

Common Types of Timber Hangers

Different timber hanger designs are available depending on the structural requirements and the type of joist installation.

Hanger Type	Best For	Typical Applications
Standard Timber Hangers	General joist installation	Floor joists, timber framing and stairwell trimming
Long Leg Timber Hangers	Deep or under-slung joists	Loft conversions and deeper structural floors
Mini Timber Hangers	Light duty joists	Ceiling joists, decking frames and loft hatches
No Tag Timber Hangers	Fast installation	General joist fixing with fewer nails required

Why Timber Joist Hangers Are Used

Timber joist hangers are used because they provide a fast and reliable way to support joists in structural timber construction.

They are commonly used for:

• floor joist installation
• timber framing
• loft conversions
• decking structures
• stairwell trimming

Using joist hangers helps ensure the load from the joist is transferred safely into the supporting timber member.

Galvanised vs Stainless Steel Timber Hangers

Timber joist hangers are commonly manufactured from pre-galvanised steel, which provides good protection against corrosion in normal building conditions.

For environments where timber structures may be exposed to moisture or corrosive materials, stainless steel hangers can provide additional durability.

Material	Advantages	Typical Use
Pre-Galvanised Steel	Cost effective and suitable for most structural timber work	Internal floor joists, timber framing and general construction
A2 Stainless Steel	Higher resistance to corrosion and chemical reaction	Green oak structures, exposed environments and damp conditions
