There will always be that nagging question that lingers behind your thoughts when planning to construct your house. “How will this structure last 30-40 years?” I have spent many years observing construction across the country and can state with certainty, the type and quality of steel used on your building will have an enormous effect on the strength and longevity of your dream home. So let’s take a very simple look at the various types of Steels used in construction.
TMT Bars – The Backbone of Every House
All house builders today are using TMT bars in their construction of homes. TMT bars take a long process of heating and cooling. They become extremely durable on the outside and very flexible on the inside.
Because of this, they have a lot of strength and can resist earthquakes. In addition, TMT bars bond excellently with concrete.

Amman-Try offers three grades of TMT bars:
- Fe500
- Fe500D (I recommend this grade for the majority of houses)
- Fe550D (This grade is ideal for large buildings)
The size of TMT bars starts from 6mm to 32mm in diameter. TMT bars can be used with safety for the construction of columns, beams, slabs, and foundations.
CRS Bars – Ideal for Coastal & Humid Places
Corrosion Resistant Steel (CRS) rebar has copper and chromium added to its alloy composition which helps prevent corrosion on steel rebar caused by exposure to salt or damp conditions. Even though CRS rebar is somewhat more expensive than regular steel rebar, the investment will save owners from a lot of headaches down the road due to corrosion caused by the elements.
RMS – Ready Made Steel Rings
This is one product that many builders have started loving. RMS (Ready Made Steel Rings / Stirrups) means you don’t have to get your labourers to cut and bend rings at the site.
They come ready with accurate sizes and proper 135° hooks. This saves time, reduces labour cost, cuts down wastage, and gives much cleaner and stronger work.

Frequently Asked Questions
Which steel grade is best for normal house construction?
For most houses and villas, Fe500D TMT bars are the best choice. They give good strength along with excellent flexibility and safety. If your plot is near the sea, choose CRS Fe500D instead.
What is the difference between Fe500 and Fe500D?
Fe500D has better ductility (flexibility) and lower sulphur & phosphorus levels. This makes it safer and more suitable for earthquake-prone areas compared to regular Fe500.
What is RMS and what are its benefits?
RMS stands for Ready Made Steel Rings or stirrups. They come pre-fabricated with accurate sizes and proper 135° hooks. It saves time, reduces labour cost, minimizes wastage, and gives stronger bonding with concrete.
Are CRS bars necessary for coastal areas?
Yes. In coastal and humid areas, normal steel rusts faster. CRS bars have special corrosion-resistant properties, so they last much longer and reduce future maintenance issues.
Does Amman-Try manufacture all these steel products?
Yes. Amman-Try manufactures high-quality TMT Bars (Fe500, Fe500D, Fe550D), CRS Bars, RMS Rings, Steel Billets, and Steel Pipes & Tubes with ISI certification and strict quality standards.
