Mild Vs. Stainless Steel for Security Door Construction

At FSM we have considerable experience working with steel to construct security doors. We specialise in mild and stainless steel and can confidently say that there are significant differences between the two.

This article will cover some of the differences and talk about the benefits and drawbacks of each that customers should be aware of before deciding on what is right for them.

What are the key features that every security door should have?

There are a lot of factors to consider when it comes to choosing a security door. Below is a list of key considerations before deciding on the type of door that you want constructed.

  • The level of security required
  • Budget considerations
  • Compatibility with existing property design
  • Supply and installation
  • Safety standards and compliance

At FSM, we specialise in the construction of stainless steel and mild steel doors. The factors listed above will influence the decision you make between mild and stainless steel. Some of the differences are outlined below.
 

What are the benefits of constructing a security door from mild steel?

Mild steel is favoured for many reasons when it comes to construction.

  • High strength-to-weight ratio} this means that large loads can be supported without extra weight being added i.e., mild steel functions as a lightweight metal while still being durable.
  • Weldable} due to the chemical composition of mild steel, it can be welded easily using simpler and cheaper welding techniques
  • Ductile} mild steel’s low carbon and high melting point makes it more ductile compared to other metals and as such, desirable when it comes to forming into different shapes and profiles.
  • Cost-effective} mild steel is relatively cheap to buy, and process compared to stainless steel.

 

What are the benefits of constructing a security door from stainless steel?

People typically go for stainless steel because of the appearance of the metal; below are some of the other reasons that stainless steel is a popular choice for door construction.

  • Durability} stainless steel is highly resistant to rust, corrosion and discolouration, which makes it ideal for buildings that are exposed to harsh weather conditions and environments prone to humidity, polluted urban areas and coastal regions.
  • Wide range of surface finishes} from brushed satin finish for areas requiring low reflectivity and metallic appearance, a highly polished finish which is more suited to areas where cleanliness and hygiene are required or painted for a decorative finish.  
  • Low cleaning and maintenance} stainless steel maintenance costs are lower because the metal’s high strength, scratches are unlikely and if they do occur, they can be cleaned off using appropriate surface treatment; graffiti and ink can be removed easily using an appropriate solvent

 

What are the drawbacks of mild steel and stainless-steel?

While mild steel is favoured for its versatility, it has a lower tensile strength than stainless steel and very low corrosion resistance which can pose some challenges when it comes to retaining its appearance. Therefore, it is essential that the surface is thoroughly clean before applying any paint, that the right type of paint is being used and that a primer has been applied prior to the topcoat. This provides an extra protective layer against corrosion. However, any damage incurred after painting must be treated accordingly to protect against the onset of corrosion.

The main drawback of stainless steel is cost due to its alloying elements which provide the anti-corrosion properties. It’s more expensive to buy as a raw material and it’s more costly to process than mild steel in the fabrication/production stage and painting, if that is the desired effect.
