Concealed double door floor bolts
While closed or locked, the concealed double-door floor bolts are hidden in the floor and the door edge grooves. This aesthetic appeal makes them well-suited for residential and коммерческие premises, where decoration is as crucial as functionality. These bolts provide excellent security and alignment, preventing doors from moving or sagging.
Surface-mounted double door floor bolts
Unlike concealed bolts, surface-mounted floor bolts are fixed on the door's top and bottom surfaces and the floor. Surface-mounted bolts are relatively easy to install, making them suitable for retrofitting and where quick installations are needed. Although they are visible and may be less integrated into the interior design, surface-mounted bolts provide reliable security and door control.
Automatic double door floor bolts
When a door is closed, these bolts extend automatically by incorporating a latch mechanism, reducing human error. Floors with automatic bolting are ideal for high-traffic areas where doors must be securely closed but where manual locking might be neglected. They provide more convenience while increasing security.
Manual double door floor bolts
Typically, these bolts need manual rotation to lock or unlock. They are mostly installed on the main entry points, where security is of utmost importance and where human verification is not a problem, Manual bolts are also suitable for residential applications, where the door owner's control over access is important.
Heavy-duty double door floor bolts
These are designed for large or high-traffic buildings. Heavy-duty bolts are made of long-lasting steel or reinforced alloys, ensuring that the locking mechanism will last a long time under severe strain. These bolts can withstand heavy use and can help prevent security breaches.
Floor bolts are available in different materials: steel, brass, stainless steel, and aluminum. Each material has its own advantages, including tensile strength and resistance to corrosion, specifically designed for use in different environments and, therefore, in various weather outlooks. The surface finish of the material, whether polished, brushed, or galvanized, is crucial to its functionality and aesthetic appeal.
Steel is a frequently used material for heavy-duty bolts due to its extreme strength and durability. Steel can wear out if used in conditions of high humidity or exposed to salt air regions since it is prone to rust without proper treatment. To increase the life of steel bolts, one must apply corrosive-resistant finishes such as zinc plating or powder coating.
Bolts manufactured from brass are highly resistant to corrosion, which makes them fit for applications such as marine or outdoor where exposure to moisture is likely. Besides, brass is aesthetically pleasing and can easily be integrated into decorative motifs. Even though brass is stronger than steel, the strength of brass is weaker, thus making it suitable for lighter applications.
For applications requiring additional protection against corrosion, exposure to extreme temperatures, and work in hostile environments, stainless steel floor bolts are preferred because of their highly resistant composition. Stainless steel bolts, which are strong and require minimal maintenance, are frequently used in industrial and marine applications.
Last but not least, aluminum floor bolts are lightweight, and bolted doors can therefore be easily handled. In addition, aluminum is corrosion-resistant, making it ideal for applications in which weight and exposure to elements are critical considerations. Heavy-duty applications are not suitable for aluminum bolts due to their lower strength compared with steel or brass.
Retail stores and shopping malls
Double door floor bolts in retail stores and shopping malls help in the control of traffic and guarantee the doors are securely closed after operating hours. Automatic bolts can operate seamlessly in high-traffic conditions so that doors remain securely locked without requiring much intervention from customers.
Office buildings
In most office buildings, the use of double floor bolts under doors is common for restricting access to specific areas such as server rooms or storage mauve, where one needs great security. Manual or automatic bolts are often used on the main entrance to enhance security and access control.
Hospitals
Hospitals are busy areas with many people visiting; thus, it is essential to keep doors secure, especially in sensitive areas such as operating rooms and pharmacies. Automatic double-door floor bolts are convenient for securing swinging doors in these areas while effortlessly allowing people to go in and out.
Educational institutions
Double floor bolts are extensively used in schools, colleges, and universities to enhance security and control access to various facilities. Locks on main entrances should be manually or automatically handled, whereas in restricted areas, manual locks are more common ( warehouses, libraries, labs, etc.).
Industrial facilities
Industrial settings encounter heavy traffic and usually have large doors; thus, heavy-duty floor bolts are suitable for securing these doors. These bolts are designed to survive adverse conditions, including exposure to chemicals and heavy equipment and frequent opening and closing.
Hotels and hospitality industry
In hotels, double-door floor bolts are commonly found in ballroom entrances, conference rooms, and dining areas. Automatic bolts are especially useful as doors close behind themselves without needing extra effort from visitors, thus a good guest experience and security.
Type of floor bolt
While choosing a double-door floor bolt, one should consider the appropriate type for the given application. While surface-mounted bolts are easy to install and suited for retrofitting, concealed bolts are for applications where aesthetic value is important. For high-traffic areas, automatic bolts offer better convenience than manual ones.
Material and durability
The material used to make the floor bolt is critical in determining its durability. While brass has excellent corrosion resistance and can be used in marine and outdoor applications, steel is suitable for long-term, heavy-duty use. Stainless steel for extreme conditions and aluminum for light applications.
Size and strength
The size and strength of the floor bolt should be considered since it should correspond to the door's size and weight. A large or heavy door requires a strong bolt to provide security and avoid strain on the bolt mechanism. Ensure that the chosen bolt fits with the relevant hardware for proper functionality.
Ease of installation
When selecting a floor bolt, the installation process should be considered, particularly when retrofitting an existing door system. Surface-mounted bolts are much easier to install than concealed ones. Automated bolts offer convenience in door security but may also add complexity to the installation.
Security features
Look for security-related features that make the floor bolt more secure. Some floor bolts incorporate anti-drill shields, which makes unauthorized access through manipulation hard. Consider bolts with keyed locking mechanisms or those that can be locked by using a key for added protection.
Cost and maintenance
This is so regarding which floor bolt to go for. While high-end materials give better security and durability, sometimes they are worth it. More maintenance is usually required for less durable bolts. Therefore, one should consider the long-term expenses of replacement and maintenance.
