Slotted, Solid, Punched Angles
Slotted, Solid, Punched Angles are equal steel angles, slotted along their length, punched to a drawing, or plain. They bolt together into bracing, stands and light frames for solar arrays and other structures without drilling on site. Specify size, thickness, type, finish and the quantity you need.

Slotted, punched or solid
Slotted angle takes bolts anywhere along its length; punched angle has holes at the positions on the drawing; solid angle is drilled or welded as needed.
1 x 1 to 4 x 4 in
Equal angles 1 x 1 to 4 x 4 in (25 x 25 to 100 x 100 mm), 20Ga–8Ga (1–4 mm), painted in yellow, green or black, or galvanized.

Bolt through the slots
The angle is cut to length and bolted to the posts, rafters or other angles through its slots or punched holes. Slots let the brace be set to the exact position before the bolts are tightened.
Common applications
Where it is used.
Solar table bracing
Diagonal braces between posts and rafters stiffen each table. Punched angles match the hole positions on the drawing.
Rooftop and elevated frames
Raised frames on flat roofs are braced with angles. Light sections keep the roof load down.
Stands and racks
Equipment stands, cable supports and shelving are bolted from slotted angle. Colours identify frames on site.
Questions answered
Common questions.
What is slotted angle called in other markets?
In the UK and Australia it is slotted angle, sometimes slotted steel. In other languages it is a cornière perforée in French, a Lochwinkel in German, an angolare forato in Italian and an ángulo perforado in Spanish.
What sizes of angle does Corona make?
Equal angles from 1 x 1 to 4 x 4 in (25 x 25 to 100 x 100 mm) in 20Ga to 8Ga (1 to 4 mm) steel, slotted, punched to drawing or solid. They come painted in yellow, green or black, or galvanized. Slotted angle bolts together without drilling on site.
