Pemilihan jenis-jenis besi untuk membuat pagar atau membuat jeriji@gril rumah amat penting kerana dari segi keperluan keselamatan dan kelengkapan bagi sesebuah rumah ia juga bergantung kepada bajet seseorang samada memillih jenis besi biasa (harga rendah) atau memilih rekabentuk yang menarik (high budget).
Kebiasaan jenis-jenis besi era sekarang (tahun 2012-2015) kebanyakkan memilih jenis besi mild steel, wrought iron dan stainless steel. Besi mild steel jenis besi biasa nipis, mudah ditempa dan ringan. Manakala jenis besi wrought iron dan stainless steel adalah jenis besi yang baik dan harga RM20.00-RM35.00 sekaki ke atas serta bergantung jenis rekabentuk yang dikehendaki.
Jadual di bawah menunjukkan perbezaan antara ketiga-tiga jenis besi:

Material
|
Steel
possesses greater tensile strength than wrought iron
Contains
a moderate amount of carbon (between .06% and 2%)
Steel is any alloy of iron, consisting of 0.2% to 2.1% of carbon, as a hardening agent. Besides carbon, many other metals are a part of it. They include chromium, manganese, tungsten and vanadium. |
contains
pure iron with a glassy material which is iron silicate
Wrought
iron: Contains very little carbon (less than
.035%). |
Stainless
steel is made up of iron, chromium, nickel, manganese and copper. The
chromium is added as an agent to provide corrosion resistance.
