Product Description

Corrugated metal roofing is a metal sheet that is roll-formed into metal panels. These panels are then attached to the roof with screws. The traditional shape of corrugated sheet metal is round and wavy. It is low cost, lightweight, durable, energy-efficient, long-lasting, and easy to install. Corrugated metal roofing is an excellent alternative to asphalt shingles or clay tile roofs. It is used for commercial and residential applications and both metal roofing and metal siding projects.

A corrugated metal panel, as described here, is not a single product. These units are manufactured all around the world and are common as low-cost roofing solutions. Though often referred to locally as iron, aluminum, or metal sheets, typical corrugated roofing sheets are made of steel. Not all are galvanized, and they vary from 27 gauge to 10 gauge. A standard sheet is one meter wide with a corrugated wave period of approximately 15cm and a peak to peak amplitude of 5cm. Sheets typically come in three lengths: 3 meters, 2.5 meters, and 2 meters. There are many companies and distributors; therefore, the links provided here are, for example, only.

Target users are Consumers, developers, or international aid organizations seeking inexpensive shelter solutions. Low-income housing owners and affordable housing/realty developers are some of the main users of this product. In addition, international non-government organizations often use metal panels to construct school and community scale building projects.

Distributors / Implementing Organizations

Most urban centers have the resources to cut and mold such simple roofing sheets. The rolls of raw steel are often imported.

Manufacturing/Building Method

As one of the most common building materials globally, corrugated metal panels have standard applications and informal, recycled uses. In "Other Information" there are a few notable articles written by practitioners in the field. These articles cover manufacturing and construction methods and the pros and cons of structures built with the product.

Suitable Climates

Most effective in dry, mild climates. Effective in warm climates when paired with a dropped ceiling.

Design Specifications

A standard sheet is one meter wide and comes in three lengths: 3 meters, 2.5 meters, and 2 meters. Not all are galvanized, and they vary from 27 gauge to 10 gauge. The panels have a corrugated wave profile period of approximately 15cm and a peak to peak amplitude of 5cm. Aligned on roofing structure, overlapping one peak and valley, the product effectively covers 80cm. The corrugation creates a flexible width and rigid length.

Product Schematics

Technical Support


Replacement Components

The rusty panels can be replaced easily when assembled properly.


As the panels rust and become less effective, they are often consolidated to contribute to the wall, window, door systems, and informal constructions. Non-galvanized sheets are more prone to rust than the galvanized ones.

Manufacturer Specified Performance Parameters


Vetted Performance Status



Typical panels themselves do not present health risks. However, when placed upon low structures with poor ventilation, solar gain can transfer substantial heat to the interior. This can create unfavorable conditions for occupants.

Complementary Technical Systems

Panels are typically paired with framed roofing structures. Roofing nails, with a 1.5cm dia. cap, are typically located on every other peak. Sealing washers are preferred. In warm climates, dropped ceilings are important for both thermal and acoustic (during rains) comfort.

Other Information

It is important to pair corrugated metal roofing with proper ventilation or a suspended ceiling to minimize solar heat transfer to interior spaces and reduce acoustic transmission when it rains.

    As per Bob: Trained
    users imply that training processes and support materials will be made
    available. Ongoing application and
    service support will be required.
    Trainers will be required to develop user guides and training

  4. Robert Hauck says:

    All medical device manufacturers must have the ability to collect customer complaints, evaluate them and address each of them. No mention of this regulatory requirement is made in the product specifications.
