Grills are a great security and design feature. There are two types of window grills: eternal fixed and internal fixed. The former are used in commercial buildings, basement windows, alleyways, windows, etc; while the latter often form screens, and are available in a variety of designs and for various security levels. Architect Aman Gandhi gives the different types and materials used in window grills.
1 Iron:
This is the strongest and heaviest compared to all other materials used for grills. It can be moulded into various shapes and sizes and costs less. However, if it comes in contact with too much moisture and humidity, it will rust. To prevent iron grills from getting rusted, regular painting and maintenance is a must, which is expensive.
2Cast iron:
Available in a variety of sizes, shapes, designs and patterns, cat iron grills are extremely durable and protect from adverse weather conditions if used properly. The only disadvantage is that it is susceptible to moisture.
3Wrought iron:
As far as properties are concerned, the features of wrought iron window grill are similar to cast iron grills except its thickness and toughness. Since it is thinner, it can be easily sawn to create uneven textures and is mostly used for decorative purposes.
4Steel:
This option is durable and looks good in external and internal spaces. Available in different patterns, steel grills are strong and heavy in nature and can resist moisture.
5Stainless steel:
This material is rich in nature and expensive compared to steel. Aesthetically, it has more visual appeal than iron and requires little maintenance. It does not get affected by moisture and does not get tarnished. It is a preferred option over steel.
6Sandstone:
This soft stone is sculpted to form decorative grilles which do away with the need for shutters as the screen itself is sufficient to provide adequate ventilation. These are available in several patterns and colours.
7Mild steel:
This option costs much less and is easily available. It comes in simple designs like straight bars or square grids. However it is not as tough as stainless steel.
8Aluminium:
Easy to maintain and durable, this is the lightest among the material choices for grills, and comes in various designs. Being rustproof, it does not ignite easily. Therefore, it is widely used in kitchen windows and shafts. The disadvantage is that it is not as tough and strong, when compared to iron and steel, and can be cut easily.
9Wood:
It is mostly used in high budget residences as it is rich in nature and visually appealing. Wooden grills are available in fixed and removable versions, but not suitable for security purposes. Also, wood requires regular polishing and painting, and therefore the maintenance cost is high when compared to other materials.
