CORRUGATED ROOF SHEETING IN SOUTH AFRICA: YOUR GUIDE TO YOUNGMAN ROOFING’S VICTORIAN PROFILE

Corrugated roof sheeting, often called Victorian Profile or S-Rib, continues to be one of the most trusted roofing solutions in South Africa. Its familiar wave pattern, reliable water-shedding qualities and dependable performance across different climates make it a preferred choice for residential projects, agricultural structures, workshops and commercial spaces.

Youngman Roofing & Insulation manufactures its corrugated profile using a complete range of premium-coated steels, including Clean COLORBOND™, Clean COLORBOND™ Ultra, ZINCALUME®, COLORPLUS®, COLORPLUS® Ultima, ZINCAL, and galvanised steel. These options allow architects, contractors and homeowners to match materials to specific environmental conditions, whether inland, coastal or in high-rainfall regions.

WHY CORRUGATED ROOFING CONTINUES TO PERFORM IN SOUTH AFRICA

Built for Local Weather

The sinusoidal shape allows water to run off efficiently, which is especially important in regions like the Western Cape where winter rainfall is heavy. Inland areas, which are affected by wind, fluctuating temperatures, and dusty conditions, benefit from the profile’s consistent performance.

Strong Value for Money

Corrugated sheeting offers dependable spanning performance while remaining cost-effective. It suits both new developments and re-roofing projects where long-term durability and practical installation are key.

Versatile Across Sectors

Its lightweight nature and ease of handling make it suitable for:

• Homes, cottages and extensions

• Agricultural sheds and utility buildings

• Workshops and small industrial structures

• Walkways, patios and veranda cover

• Vertical cladding and decorative façades

This flexibility has kept the profile relevant across a wide range of building types.
