Galvanised steel is great for outdoor construction and other applications where the steel will be exposed to the elements. Galvanised steel angles are available in a variety of sizes and grades to meet different needs.

Angle trim, also known as corner trim or angle iron, is a type of trim used to finish and protect the edges of drywall or plaster walls and ceilings. It is made of metal, usually galvanised steel, plain steel or aluminium, and is used to create a neat, finished edge where two walls or a wall and ceiling meet. Angle trim is also used to reinforce the corners of a wall, helping to prevent cracking and damage. It is typically installed by nailing or screwing it to the wall or ceiling, then covering it with joint compound and smoothing it out to create a seamless finish.

Angle iron is typically measured by its legs, which are the two sides that form the angle. The legs are measured in inches or millimetres, and the thickness of the angle iron is also typically measured in inches or millimetres. Additionally, the angle of the angle iron, typically measured in degrees, can also be specified. For example, a common specification for angle iron might be “2 x 2 x 1/4 x 90 degrees,” which indicates that the legs of the angle are 2 inches by 2 inches, the thickness of the angle iron is 1/4 inch, and the angle of the angle iron is 90 degrees.

We always use millimetres. Our our angle may measure something like ’20 x 20 x 3mm’. This is 3mm thick with 20mm legs.

To cut angle iron, you can use a variety of tools including a metal cutting saw, a hacksaw, a cutoff wheel, or a plasma cutter. Each tool has its own advantages and disadvantages depending on the specific cutting needs and the resources available.

• A metal cutting saw, such as a chop saw or a mitre saw, is great for making precise, straight cuts on angle iron.
• A hacksaw can also be used to cut angle iron, but it requires more physical effort and may not produce as clean or precise of a cut.
• A cutoff wheel, such as an angle grinder with a metal cutoff wheel attachment, can be used to make quick cuts on angle iron, but it can be difficult to make precise cuts and the sparks generated can be dangerous.
• A plasma cutter is a powerful tool that can make quick and precise cuts on angle iron, but it can be expensive and requires a power source.

It is important to use the appropriate safety equipment and follow the manufacturer’s instructions for the tool you choose.

Angle iron is a strong, durable material that is commonly used in construction and fabrication. Its strength comes from its L-shaped cross-section, which provides structural support and stability. Additionally, angle iron is made of steel, which is known for its high strength and durability. The thickness of the steel and size of the angle iron also affect its strength. It is also commonly used for corner reinforcements, bracing, and supports in structures.

Galvanised steel is steel that has been coated with a layer of zinc to protect it from rust and corrosion. The zinc coating acts as a barrier that prevents oxygen and water from reaching the steel, which slows down the rusting process. However, it is not completely rust-proof and over time, the zinc coating can wear away, exposing the steel to the elements and allowing rust to form. In addition, galvanised steel can still corrode if it is exposed to certain chemicals or if the zinc coating is damaged.

Yes, galvanised steel can bend, but it may be more brittle and less ductile than uncoated steel. The galvanization process, which involves coating the steel in zinc, can make the steel more prone to cracking or breaking when bent. The thickness and grade of the steel can also affect its ability to bend.

Yes, you can weld galvanised steel, but it does require some special considerations. Galvanised steel is coated with a layer of zinc to protect it from corrosion. When welding, the heat from the welding process can cause the zinc coating to vaporize, creating zinc oxide fumes that can be hazardous to inhale. To minimize this, it is recommended to use a lower heat setting on the welding torch and to use proper ventilation to disperse the fumes. Additionally, it is also recommended to use a welding wire specifically designed for welding galvanised steel.

Yes, you can paint galvanised steel, but it does require some preparation to ensure proper adhesion. Before painting, the galvanised surface should be cleaned thoroughly to remove any oils, dirt, or other contaminants that may be present. This can be done using a degreaser or a solution of water and detergent.

It is also recommended to lightly sand the surface to help create a better bond between the paint and the galvanised surface. After cleaning and sanding, the surface should be rinsed off thoroughly and left to dry completely before applying a coat of primer specifically designed for use on galvanised steel. After the primer has dried, you can apply your desired paint.

Galvanised steel has a relatively low heat resistance compared to other types of steel. The zinc coating on the surface of the steel has a melting point of around 787 °F (420 °C). When exposed to temperatures above this, the zinc coating can start to melt and lose its protective properties. In addition, the heat from welding or other high-temperature processes can cause the zinc coating to vaporize, releasing zinc oxide fumes.

It’s important to note that the heat resistance of galvanised steel also depends on the thickness of the zinc coating. Thicker coatings will have a higher heat resistance than thinner coatings.

For high-temperature applications, it’s recommended to use other types of steel or coatings that can withstand higher temperatures. In case of high temperature application, it is always recommended to consult with us first or with an expert metallurgist.

Galvanised steel is machinable, but it may be more difficult to work with than uncoated steel due to the zinc coating. The zinc coating can cause adhesion issues and increase cutting resistance. Additionally, the zinc fumes generated during machining can be harmful to inhale, so proper ventilation and respiratory protection should be used. It is also recommended to use high-speed steel or carbide cutting tools, as they are more durable than regular steel tools and can withstand the increased cutting resistance.

Hello I am studying for my PE Civil Structural Exam. I was wondering for this question why would you not use the yielding formula from
AISC 360-16 F.10:


Question:


Solution:
I'm a bit confused by your question

The calculations you've provided have My = 1/6bd2 and Mp = 1/4bd2 - isn't that incorporating the 1.5x factor?
This is based on whether your critical point (angle leg moment capacity in this case) is likely to be subject to local buckling or whether it can achieve a full section plastic capacity
It's not guaranteed that every section can do this, though I typically do make this assumptions for angles
So F.10 says that Mn = 1.5My, I do not understand why they didn't just use this instead they used Mn = Mp <= 1.6My. Why use this? I see that in F.11 for rectangular bars and rounds they use Mn = Mp <= 1.6My, but why use this for angles? Sorry if this is hard to understand. The flexure is about a single leg of the angle. The formula you posted is for flexure of the gross cross section.
A single leg of the angle in flexure is treated like a rectangle, this would send us to AISC F11. The first equation you post from F10-1 is for single single angles loaded along their length. The situation you have in the problem is for the bending of a single leg of the angle, which effectively behaves as a rectangular bar, which is controlled by section F11 in AISC. You'll see that the Yielding equation in that section is Mn = Mp = FyZ ≤ 1.6My. Just a follow up at the end why did they divide the moment by 4-3/8? I know the answer is suppose to be P but I am confused how dividing it by that gives P? 9.11 is the moment capacity, right?
But it's the moment capacity at the critical section within the leg of the angle
The force P is dimensioned as 4" from the face of the concrete, but the leg of the angle starts 3/8" short of that
So you get a small bump in max force allowed That "by inspection P controls" has me lost. What does that even mean, is there some other criteria I'm supposed to dismiss out of hand?

The 1.5My is for bending along the length of the angle. That's why they didn't use it. oh I see, thanks

[Edit]
But isn't the modulus a cross-sectional property? I was thinking the 8" would be used for flexural (EI) rather. I would argue the proposed solution is incorrect for the shown configuration, the critical bend plane is actually in the vertical leg. The load configuration shown will cause the angle heel to pull away from the wall and the vertical leg will bend about the anchor.

So the critical value for P should be 9.11 in-kips / (4 in-(3/16 in)) = 2.39 kips. where 3/16" comes from 1/2 * 3/8 in. Bulb, the section being analyzed in the example is the rectangualar section of the bottom leg in bending.

The problem has us thinking about the single leg of the angle resisting bending like a cantilever. That leg has it's own cross-section properties (S,Z,I,etc)

In this problem, the rectangualar cross-section is 8" wide and 3/8" thk.

Celt83 said: I would argue the proposed solution is incorrect for the shown configuration, the critical bend plane is actually in the vertical leg. The load configuration shown will cause the angle heel to pull away from the wall and the vertical leg will bend about the anchor.

The question states assumptions that the anchor is sufficient and the concrete is sufficient. They could have worded it better but its presented as the vertical leg stays put. I agree with celt. Niether bolt nor concrete need to fail for the heel to move away from the wall.



damn he beat me to it.
