Rondo produce a wide range of Top Hats for a variety of uses including internally or externally and on vertical fascias and soffits. Top Hats are often used where there is a higher wind loading or where heavy duty sheeting is to be installed.

The Top Hats come in both medium gauge (0.75bmt) and heavy gauge (1.15bmt), two different face widths, 50mm and 75mm, and four different depths, 15mm, 25mm, 35mm, and 50mm. Each Top Hat is manufactured from G200 Z275 Gal Steel.

Rondo also produce a range of complementary fixing cleats that enable the adjustable fixing of Top Hats to steel or masonry/concrete substrates as well as to steel stud framing, allowing for plumb or leveling of the cleat to the structure and of the Top Hat onto the cleat.

Some facade systems require the installation of Top Hats vertically and there will be occasions where steel studs do not coincide with the Top Hat spacing requirement.


Rondo have a range of Steel Angles available, including heavy duty and slotted angles.

Heavy Duty Steel Angles suit both lightweight autoclaved aerated concrete panel systems (AAC) and steel framing requirements for facade systems. They can be used to strengthen internal corners of façade systems, in the construction of bulkhead framing or in a variety of situations requiring bracing or stiffening.

The Slotted Steel Angles can be used for head and base fixing for AAC panel systems.

They also produce ‘C’ Channel components that are designed for use with Speedpanel products and also offer Double-punched Nogging Track that is suitable for back-to-back configurations for Rondo Steel Stud or MAXIjamb®.
