This section provides an overview for corrugated sheets as well as their applications and principles. Also, please take a look at the list of 10 corrugated sheet manufacturers and their company rankings.

A corrugated sheet is a board-like building material made of polycarbonate (a light-transmitting polyethylene material), light-shielding slate, hard galvalume steel, and PVC (the same material used in polyethylene buckets), all of which are pressed into a corrugated sheet.
The corrugated shape of this building industry material is effective in increasing the strength of vertical loads when used as a wall material, and in providing efficient rain protection during heavy rainfall.
For temporary construction sites and storage sheds, corrugated sheet offer outstanding cost performance because a single material can be used to make both roofs and walls.
The main uses of corrugated sheets are roofs and walls of simple storage sheds and bicycle parking lots, warehouses for temporarily storing agricultural equipment in fields, and slates are commonly found as roofing materials for factories and plants.
Rigid polycarbonate and corrugated sheets of PVC material are often used as top-light fittings because of their high strength and brightness. In particular, thick rigid polycarbonate is strong enough to be used on stairs, so it is a material that can be used as a flat roof to climb up.
Driving through the suburban countryside, one often encounters nostalgic scenes of houses with extended sheds and eaves made of PVC corrugated sheets.
Features of corrugated sheets are that they can be easily used for siding such as simple houses. You may also see corrugated sheets used for oyster shacks at the seaside or for aquaculture processing work.
Galvalume corrugated sheets are low-cost exterior wall material that is easy to crimp on and off for repairs, and its matte rust-preventive coating makes it popular as a heavy, modern siding material for low-cost housing. The siding that surrounds the perimeter with a single roll plate is seamless and aesthetically pleasing.
The convex and concave features of corrugated sheets are not only wavy, but also trapezoidal, square, and other metalworking press variations. The reason why it is wavy is that it has the advantage of being stronger and less likely to break than flat sheet metal materials when placed vertically.
On a roof, rainwater accumulates quickly and has a large flow rate, so a slight sloping of one side of the roof has the advantage of excellent drainage. As a building material, it has this reasonable rationality.
To attach corrugated sheets to an object, fasteners are used to secure the corrugated sheets to the object. There are various types of fasteners, such as screws, nails, and hook bolts, that are specially designed for the substrate to which the corrugated sheets are attached.
To fasten corrugated sheets to an object, drill a hole at the top of the corrugated sheets and insert a screw or nail into the hole.
When corrugated sheets are stacked horizontally, the edges of the corrugated sheets must have at least a 2.5-mountain overlap (or 1.5-mountain overlap if the wave pitch is large) between them before they are secured to the object. Also, be sure to fix the overlapping portion to the object with fasteners.
If hook bolts are used to fasten corrugated sheets to the object, hook the hook bolts onto the angles and tighten the nuts.
Corrugated sheets come in a variety of materials, and the tool used for cutting must be selected according to the material.
One of the cutting tools, corrugated sheets scissors, has a corrugated blade to fit the corrugated sheets and are suitable for cutting corrugated sheets made of polyvinyl chloride. For cutting glass net or polycarbonate corrugated sheets, the use of a saw is more appropriate. If the corrugated sheet is hard such as colored tin or galvalume, it is appropriate to use an electric saw.
When cutting corrugated sheets with scissors, it is recommended that work gloves be worn during the cutting process, as there is a risk of injury from the cut edge of the corrugated sheets.
It is also important to mark the cutting position in advance to avoid overcutting and incorrect cutting position. Also, before inserting scissors, it is recommended to make a cut in the area to be cut using an acrylic cutter or similar tool to facilitate the cutting process.
When cutting corrugated sheets with scissors, use the base of the scissors, not the tip, to facilitate the cutting process.
