S235JR angle iron is a common type of steel made to EN 10025-2 standards. It's a plain steel that comes in L shapes, with either equal or unequal sides. People like it because it's strong enough, welds well, and is easy to work with. That makes it a good pick for many jobs where you need to hold things up or make frames.
We make and sell S235JR angle iron, usually by hot-rolling it, then straightening it and checking its size. This type of steel is made to be strong when you use it normally, and it's easy to cut, drill, and weld where you are working. Its yield strength is about 235 MPa, so engineers can plan safe builds without wasting money on extra material.
Chemically, it's made with low carbon, plus some manganese and silicon. This mix makes it tough and less likely to crack when you weld or bend it. S235JR angle iron is often used when you need something safe, easy to get, and not too costly, like for building frames, support pieces, and other small steel builds. When we say S235JR angle iron here, we're talking about the stuff we make and sell following international standards.

Features and Advantages

- This stuff welds really well, which is a big plus. Because it doesn't have much carbon, you can use regular welding tricks without warming it up first. This means you can get the job done faster and cheaper, which is great if you're on a tight deadline.
- It's also made with care to be the exact right size. We watch the length, thickness, and straightness when we roll and finish it. This means less tweaking when you put it together, and parts fit better in those prefab buildings.
- Plus, it's easier to shape and cut than stronger steel. If you're bending, punching, or doing simple machining, this type of steel keeps your tools from wearing out and is easier to work with, but still strong enough for what you need.
- This material also holds up in all sorts of weather. It stays strong and tough in normal temps, so people keep picking it for buildings and factories that need to last.
Our Strength

Jiangsu CunRui Metal Products Co., Ltd has been supplying structural steel sections to overseas markets for a while now. We get what inspections usually ask for, like checking sizes and material certificates, so we prep our paperwork to match. Because we have reliable production partners and plan our stock well, we keep our quality consistent and deliveries on time. We care more about keeping customers happy and building partnerships than just pushing big orders, which is probably why many customers keep buying S235JR Structural Angle from us.
Applications



Transportation
Service & Support
We offer practical services for S235JR angle steel that matches your project needs. We stock equal and unequal angles made to EN standards, with tight size controls for easy fitting.
We can cut the steel to length, which saves you time and trash at the job site. We also offer surface treatments such as blasting, priming, or oiling to prevent rust before shipping if you need them.
To make things simpler when unloading and sorting on-site, we can pack different sizes together and label them clearly.

FAQ
Q: Is S235JR Structural Angle suitable for welding without special treatment?
A: Yes. In most cases, standard welding procedures can be used without preheating, thanks to its low carbon content.
Q: Can you supply non-standard lengths or mixed sizes in one order?
A: Yes. We regularly provide custom cut lengths and can combine multiple sizes in one shipment to match project requirements.
Q: What surface condition is typically supplied?
A: The standard supply condition is black hot-rolled. Upon request, shot blasting or primer coating can be applied.
Q: How does this grade compare to ASTM A36?
A: They are widely considered equivalent in application. Differences mainly relate to standard requirements rather than practical performance.
Q: Do you provide inspection certificates?
A: Yes. Mill test certificates according to EN 10204 3.1 are available, and third-party inspection can be arranged if required.
