Corrugated metal is the term used to describe metal which has been fed through rolling dies to achieve corrugation. The metal used is most often steel, aluminium or iron with steel usually being the most popular. The purpose of the corrugation process is to increase the bending strength of the metal in the direction the corrugations are facing. The bending strength in directions across the corrugations is not strengthened by the process. The procedure known as Roll Forming is used to achieve the corrugations. The metal is passed through the rolling dies and then cut at the required length. The standard corrugation pattern used has a rounded shape and will take the form of the letter ‘S’ if the edge is viewed from the side. The shape of the corrugations can be changed by using a different set of rolling dies.

Usage

Corrugated metal is lightweight and also easy to transport. It is used frequently in commercial and industrial buildings particularly as corrugated metal roofing, corrugated metal siding and sometimes corrugated metal cladding. Corrugated sheet metal is strong, durable and can also be somewhat corrosion resistant if treated prior to use. Although processes such as galvanizing can be used to reduce the effects of corrosion the corrugated sheet metal roofing will still rust after a number of years. The effects of corrosion can be increased in areas close to the coast or where acid rainfall occurs. A corrugated metal roof is most likely to be found on large factories or agricultural buildings although these kinds of metal roofs are also now used on residential properties. Residential roofs will look different to commercial ones constructed using corrugated metal sheeting and can be designed to have the appearance of other less durable but more aesthetically pleasing roofing materials. A roof produced from corrugated metals is an increasingly popular choice due to the durability of the materials along with their lightweight design and ease of installation. The minimal maintenance requirements of a corrugated metal sheet over a number of years means that these materials are very often the most economical choice.

Corrugated metal sheets are a safe and secure choice of roofing material in most environments. This kind of steel roofing has considerable strength and impact resistance while also possessing the highest levels of fire resistance making them desirable in many kinds of commercial buildings. They are also effective in areas which are likely to experience termite infestation. These corrugated metal panels have been in use since the mid 1800’s when they were originally invented. Their durability, versatility and ease to work with should ensure that they remain a popular choice for use in both industrial and residential buildings for many years into the future.

Although corrugated roofing is the most common usage there are also many other roles for these metals including the production of corrugated metal pipe for culverts and storm sewers as well as many types of corrugated metal hose which can withstand very high pressures and are effective for transferring liquids and gases in industrial environments.

Corrugated metal roofing is now a popular option for commercial property owners and some residential owners. It has proven to be a secure, resilient roofing material choice since the process for corrugating metal was first developed. The strength, durability and life expectancy of metal roofs can be increased significantly using the corrugating process. Most of these kinds of roofing sheets are produced from different varieties of steel and sometimes coated with range of substances before use. Corrugated iron roofing is also used frequently. Metal roofing materials ensure that a lightweight roof is possible while still retaining a very sturdy structure. Other materials are available such as corrugated plastic roofing but metal will often provide more strength and longevity.

Galvanized and Stainless Steel

The primary types of corrugated roof sheets are produced from either galvanized or stainless steel. Galvanized steel has been used for a long time due to its low cost and excellent physical structure. A corrugated metal roof made from galvanized steel is a popular choice in many industrial buildings. The major advantage of using galvanized steel over other metal roofing materials is the resistance to corrosion which is achieved by coating the metal with another substance such as zinc. This greatly improves the ability of a roof to withstand the elements over an extended period of time although the coating can start to look unattractive after a number of years.

A Stainless corrugated steel roofing system provides natural resistance to corrosion. It does not need to be treated and so its appearance does not tend to deteriorate over time as galvanized metal roofing would. A stainless steel corrugated roofing sheet is slightly weaker than a galvanized one so it is important to decide whether looks or a strong structure are most important for the needs of your individual property. The stainless steel option would not be as suitable in environments which experience frequent and violent storms.

Corrugated roof panels produced from more specialised materials are always becoming available but usually at higher costs. Most will continue to use steel as a base in conjunction with a variety of different alloys which produce resistance to different kinds and intensities of corrosion. The stainless or galvanized metal roofing options will be suitable for the needs of most property owners but your individual circumstances may mean that investing extra money in more modern specialised corrugated roofing panels will be sensible. It is best to seek the advice of your supplier if unsure.

If you have decided to install a metal roof in your home or another small building then you may want to consider completing the work yourself. If you have a good level of construction or roofing experience then this could be a legitimate option for you. Having said that a metal roofing installation project will likely take up a lot of time so it is important to give serious consideration to whether you will be able to commit the necessary resources and whether you are actually capable of completing the metal roof installation given your current skills and experience. The type of metal roofing materials you wish to use will affect your own ability to carry out the work. For example some forms of standing seam metal roofing can be complicated to install due to the way that the panels are joined. You would usually want to be familiar with the industry installation techniques before beginning a project using these kinds of materials and it would not be a wise undertaking if you had never worked with a standing seam metal roof before. It is advisable to at least speak to a company specialising in metal roofing materials and installation in order to get a professional opinion on the levels of complexity your project will involve before deciding that you do want to complete the work yourself.

Research

It will be necessary to undertake a considerable amount of research in order to determine which of the various types of metal roofs will best suit your property and your budget along with the metal roof colours your chosen material is available in. Comparing metal roofing prices along with prices of the tools needed for the installation in your area is also a must. You will also be able to gain valuable advice while speaking to different local suppliers. While researching metal roof cost it will usually be a good idea to make some enquiries into the price of professional installation with a few different companies in order to be sure that it really is worthwhile to take on such a large project yourself. You may find that the cost of hiring professionals who have experience dealing with metal roofs is actually much more reasonable than you first thought especially if you are also purchasing the necessary materials through the same company.

Costs

In order to obtain a reasonably accurate estimate of how much the required metal roofing material is going to cost you may want to have a roofing analysis carried out. This will require you to provide the roofing company with a diagram of the roof you wish to install including measurements. The diagram does not need to be completed to a professional standard but specific information will need to be included in order to receive the most accurate quotation. It is advisable to contact companies in advance and ask each of them about the specifics they will need from you in order to perform a roofing analysis. As a quick guide metal roofing materials are typically priced within the range of $150-$600 per square making them fairly expensive. You will need to be certain about the quantities of various materials that you will require such as sheet metal roofing, shingles, tiles or corrugated metal roofing before you can have a good idea of the cost of installation for your property.

Some of the most important work to be carried out on your own roofing project is the necessary research before the construction even begins. It is essential to ensure that you are capable of installing metal roofing and have accurate assessments of the costs you will incur both financial and in time and effort. Many homeowners find that after careful consideration they would actually be better off hiring professionals to carry out the work. The installation of these kinds of roofing materials is certainly not for the inexperienced. This is true for many kinds of building work so whatever kind of project you want to complete be sure to get various roofing, building, flooring and wall quotes from a specialist contractor as well, if only for purposes of comparison.
