Therefore, hinges exist between blades. Galvanized metal sheet has its particular pattern which can be found on the texture.
Concrete Plates
It is a concrete wall made of numerous concrete plates. Due to weathering, the concrete plates have cracks, pores and dirt.

If you are going to 3D model a concrete wall, please do not miss this texture!
Corrugated Metal Sheet
It is a classical corrugated metal sheet where is commonly used to build walls of factories or construction sites.

Dirt and edge wear can be found on this texture.
Metallic Shipping Container
It is a very typical metallic shipping container that you can find on trucks. Though it is blue, its color can be changed in rendering engines or by using the sbsar file.

Dirt mark and edge wear also exists.
Corroded Iron Sheet with Rusty Scratches
This is an oxidized iron sheet on which there is numerous scratches and dents. Most of the scratches and pits corroded and are covered with rust. Besides, some of the rust is dripping down due to the rain wash.
Chain-link Metal Wire Fencing Texture
It is a chain-link fencing made of iron or steel. It is galvanized to reduce corrosion, so it can keep its shiny silver color.

Chain-link Iron Wire Fence Texture Woven in Diamond Shape
(Metal 0017)
is similar to this material except Metal 0017 is highly oxidized and has a lot of rust.
Office Ceiling Tiles
They are drop ceiling tiles in most of the offices. This mineral fiber ceiling is the most widely adopted type.It has a lot of pores on the surface.

Ceiling tiles are usually mounted on a suspended aluminum frame. Since aluminum is a soft metal. The frame can easily be deformed.

Edge wear also happens on the metal frame.
Rusty Metal Plate Texture
This is a highly oxidized iron sheet with stacks of rust formed on its surface. It is almost fully covered with oxidized substance. The rust has different colors including yellow, orange, red and brown.

The base metallic plate is more shiny than rusty materials. In fact, rust is not a reflective material.
Chain-link Iron Wire Fence Texture Woven in Diamond Shape
It is a chain-link fence made of iron or steel. Frequently, it is woven in diamond shapes which form the characteristic of this type of fences.

Due to weathering, this fence has some degrees of deformation. Rust, oxidation and dirt can be everywhere. There are some worn on wires too.
Metal Plate Covered by Scratched Paint Texture

Punched or Perforated Metal Sheet Texture with Rust
This iron sheet has a lot of holes as it is a punched or perforated metal sheet. Its surface tells us it is oxidized and a lot of reddish and yellowish rust has formed on the surface.

It is a desired material for machine cases.
Damaged Concrete Texture Exposing Rusty Rebars or Reinforcing Steels
It is a disastrously damaged concrete wall exposing thoroughly rusted reinforcing steels.

Areas around rusty concrete steels are also contaminated by rust.

The concrete surface is very bumpy and full of pits.
Oxidized Brushed Aluminum Texture with Dirt
It is a oxidized brushed aluminum plate with dirt. The oxidation reduces the reflectiveness of the metal, so the surface has uneven glossiness.

Besides oxidation, dirt also affects the colors and reflectivity of aluminum.
Rusty Metal Plate Texture with Round Cap Nails
It is a tremendously rusted metal plate. Thick layers of rust cover the whole iron surface, but the rust is thinner around round cap nails.

The rust has different colors including light brown, dark brown, orange and black.

Scratches can also be found on the rusty superficial.
Oxidized Metal Plate Texture with Round Cap Nails
This highly oxidized metal plate is full of round cap nails, but well aligned. It is usually used as covers for containers.

Dirt has accumulated around round caps as those are good places to hide debris.

Oxidation has different degrees too. It can be proved by different reflectivity.

Of course, scratches cannot be omitted for oxidized iron metals.
