Question 1

1. What is an angle lintel?

Accepted Answer

An angle lintel is an L-shaped steel lintel used to support masonry over openings. It’s typically used in single leaf walls or outer leaf brickwork.

Question 2

2. What sizes do angle lintels come in?

Accepted Answer

Angle lintels are available in lengths from around 900mm to 3600mm. Sizes usually increase in set increments to suit standard opening widths.

Question 3

3. What types of coatings are available for angle lintels?

Accepted Answer

Most angle lintels are manufactured from galvanised steel, which provides a base level of corrosion protection. This is the standard finish used across UK construction. Many products also include a secondary powder-coated finish, applied over the galvanised steel. This creates a duplex coating system that improves durability and resistance to moisture exposure. For more exposed conditions, some lintels are available in hot-dip galvanised finishes or stainless steel grades, such as 304 or 316, which offer higher corrosion resistance.

Question 4

4. Can I drill through an angle lintel?

Accepted Answer

Drilling through an angle lintel is possible, but it should be approached with care. Angle lintels are structural elements, so drilling can weaken the steel.

In most cases, small holes for light fixings, such as cables or brackets, may be acceptable if the correct tools and methods are used. Steel lintels require specialist drill bits, such as high-speed steel (HSS) or carbide bits.

However, drilling for structural fixings or large holes is not recommended without engineering approval. Removing material can reduce loadbearing capacity and create stress points within the lintel.
