Installation and Configuration of Steel Door

Overview

A steel door is stated to be the most secure way of protecting your property and people within homes, commercial establishments, and industrial plants. It is strong and stable, durable, resistant to damages, and corrosion and rusting. It offers maximum protection from fire, flood, and damages caused by intentional attacks. You can choose security from level-1 to level-4 and beyond based on the specific requirements.

Levels of Security – Design and Construction

The type of design and construction of doors for level-1 security will protect the doors from attacks with handheld tools and equipment like a hammer, chisels, handsaw, and others. You have to analyze the user manual to check the duration for which the door can withstand such attacks before the security personnel can respond to the alarms.

Level-2 security doors should be able to withstand attacks by heavy tools and equipment, often driven by electrical and mechanical force. The locking mechanism, density and dimension of the doors should be much higher than level-1 doors.

Level-3 doors will have a protection mechanism for attacks with gas-torches, crowbars, and other heavy tools. These doors can withstand floods and fire of high intensity without buckling or breaking under stress.

Level-4 can protect from explosives and other heavy tools for break-in attempts. Duration of protection will be the highest among all the levels.

Steel Security Doors – Internal Access 

Design of the steel security door has to be according to the frame and vice versa in some cases. It should have a fire-resistance for at least three to four hours without melting or buckling. Temperature tolerance limits will depend on many factors like 

Type of fire risk

Intensity of fire

Type of source

The time required for fire rescue

The intensity of a fire may vary for the electrical risks, chemical risks, fuel and flammable liquid risks, and gas risks. You need to measure the distance between the source and the fire-resistant door and also the time required for the fire to spread from the source to the door. If the source of fire is internal, you will intend to stop spreading the fire to other parts of the building.

If the source of fire is external, you will intend to protect the people and property within the room for which you have installed the steel door.

Door Installations – Location Specific 

The purpose of installing steel doors is to prevent unauthorized access from intruders and damages from hazardous elements. The type of door you need for the places will vary depending on the intensity of risk. For example, you can consider the following types of steel doors for

Production unit

Warehouse

Hazardous elements storage

Restrooms

Kitchen

Laboratory

processing units etc

The needs of corporate and business houses could be different based on the risk and level of security threats. You can choose the steel-doors based on the dimension, material, locking mechanism, and other factors that can offer maximum security.

Conclusion 

Choosing the right design and construction for the steel door can ensure the best protection mechanism for property and people in the residential, commercial, and industrial establishments.

Why and Where do I Need security doors

Protection from intrusion is the primary purpose of having Security doors in the residential, commercial, and industrial buildings. The other reasons could be securing the interiors of buildings from fire, floods, hailstorms, and other external elements. They are also highly useful in maintaining privacy in hospitals, hotels, meeting halls, etc. The most commonly used material is pure steel or in combination with its alloys.

Solid Steel Vs Hollow Steel – Usability Parameters

You might have seen solid steel doors being used in ships, yards, power plants, and industrial units where the probability of attacks with explosives is the highest. Have you ever wondered about the fire-rated steel doors that are used in commercial and industrial establishments? Well, they don't use the solid steels, rather the hollow steel doors.

The outer layers are made of high-density steel sheets that could have a thickness from a few millimetres to a few inches. The different parts of the door could be sweep-gasket at the bottom, threshold sill, chrome-plated sheets, galvanised frame, and an automatic latching system. It is one type of door you may come across. Many other forms may have steel studs, profiles, etc. These doors are extensively used for providing internal and external security to the buildings.

Hollow steel core has to be filled with some sort of insulation and stress protection materials. The general practice is to use fillers like a honeycomb, polyethene, polyurethane, and others. Let me show you how each filler works.

Steel Core Fillers – insulation and Strength Factors

The basic material used for honeycomb filling is the cardboard that is cut and shaped to fill the steel-core. Their expansion and compression ratio is negligible even in the harshest internal and external conditions.

The assembly of corrugated sheets ensures maximum resistance to heat and cold. They are packed and pressed to form a single structure. The number of layers depends on the hollow space between the steel sheets. They have the maximum resistance to stress and vertical load.

Every corrugated board has a liner, flute, and edges. The load generally has an impact on the upper and lower sections of the honeycomb. Sometimes, the load may also be diagonal or cross-sectional. The liners don’t buckle under consistent static load or dynamic load. Hence, they are recommended for the filler materials within the security doors.

The synthetic materials like polyurethane and polyethene are primarily used for insulation. Though they don't have much value for impact resistance, the ratio is reasonably good.

Security and Protection – Why and When Factors

Security is required where there is a threat of intrusion or attacks. It could be your home, commercial building or industrial buildings. You also need security from fire, floods, hailstorms, mob attacks and other forms of external damages.

What about internal risks like hazardous materials, chemicals and radioactive substances? The personnel in the plants need security from accidental exposure. These are some of the instances when you need security.

Conclusion

You can use security doors in every location that is prone to intrusion and environmental calamities. Steel is the most commonly used material in combination with the other metal alloys.
