All commercial door locks and closures are considered grade 1. That means they are the strongest and most secure for high-traffic areas and places of sensitivity (like museums, clinics, and universities). Since they are strong, they should hold up to intense use and last longer than their residential counterparts.
How Do They Differ? The difference mainly lies in the grade of the lock. A commercial lock should be at least a Grade 1 or 2 to ensure security and protection of assets. This is not to say that residential properties do not have expensive items.
Commercial locks are typically sturdier than residential building locks. According to the Builders Hardware Manufacturers Association (BHMA), a grade one lock offers advanced strength to protect commercial buildings. They can resist 360 lbs in weight, ten strikes and 800,000 cycles.
A commercial grade lock is one with a stronger rating, as determined by the Builders Home Manufacturers Association, the official trade association for manufacturers of building hardware. The Association is credited by the American National Standards Institute to perform such gradings.
Commercial door locks are locksets that are graded for commercial use. The Builders Home Manufacturers Association grades every commercial lock on a scale from one to three. If you need high-security commercial door locks, go with grade 1 or grade 2 locks.
Most commercial applications require either grade 1 or grade 2 locking hardware. Grade 1 not only meets commercial building requirements, it also provides the best security available against vandalism and heavy usage. Grade 2 meets light commercial requirements and exceeds residential building requirements.
Security Matters
Another major difference between a residential door and a commercial door is how they are secured. Unlike residences, businesses are often accessed through electrical doors as well as more conventional ones. They may also have electrified locks, keyless entry or other digital means of access.
How Secure Is It? A lock's security is denoted by its American National Standards Institute (ANSI) grade, with Grade 1 the most secure and Grade 3 the least. A builder-quality tubular lock will likely be a Grade 3, a good-quality handleset a Grade 2.
Deadbolt Locks
Deadbolt locks come in three primary types: single, double and vertical. Single-cylinder deadbolts are the simplest and can be activated from one side via a key. Double-cylinder deadbolts can be used with a key from both sides.
A commercial door is more likely than a residential one to be made of steel or fiberglass, and may be thicker than its residential counterpart.
Grade 2 – Higher Residential Security Designed to offer excellent security and durability. Used mostly for residential applications and some light commercial applications. Grade 3 – Basic Residential Security The lowest grade provided by ANSI, and the minimal acceptable quality for residential door locks.
According to the ADA Guidelines:
Handles, pulls, latches, locks, and other operating devices on accessible doors shall have a shape that is easy to grasp with one hand and does not require tight grasping, tight pinching, or twisting of the wrist to operate.
Grade 2 locks are rated for use on exterior access points for low or medium amounts of traffic. They can also be used on interior doors that require a high degree of security. Grade 2 lock applications include office spaces and the doors to storage rooms containing valuable merchandise, materials or equipment.
Available in single- and double-cylinder styles, deadbolts are rated according to their strength from Grade 1 to Grade 3. A Grade 1 is the highest grade and provides the most security.
Many times the deadbolts will have the name stamped on the face of the lock. Door knobs are a little different. Most brands of knobs do not have the manufacturer name on them. However, if you look at the latch, many manufactures will stamp their brand name on the latch plate.

Each key has a complex rounded shape, this coupled with the magnetic element makes it an extremely hard lock to pick. The only way to gain access to the door would be for the key to be cloned, and in that case, a master locksmith would need to get their hands on the original key.
CR's take: The Medeco Maxum 11TR503-19 is the strongest deadbolt across all of our lock categories. It's top-notch for drilling, withstands kick-ins very well, and is designed in a way that makes it quite difficult to pick.
The best grade of deadbolt lock is Grade 1. The grades are assigned by the American National Standards Institute (ANSI). This non-profit group was developed by the Builder's Hardware Manufacturers (BHMA) to set standards for a variety of industries.
The main difference between residential and commercial construction projects is in the name. Residential construction is when housing is built (apartments, flats, and houses), while commercial construction involves industrial facilities, warehouses, and business establishments.
Comparatively lesser cost: residential properties cost lesser than commercial properties. If you are a beginner and want to invest money in real estate, investing in residential property is a great option. Fewer complications: residential properties do not have many regulations as in the case of commercial properties.
Let's start with the basics: Residential interior designers focus on private homes, condos, and apartments. Commercial interior designers create public spaces including hospitals, healthcare clinics, schools, office spaces, retail stores, community centers, and fitness centers.
