Gang nail

Types of gang nail

A gang nail plate is a connector used in wood construction. It is also known as a truss plate or nailer. Engineers designed it to connect two or more wooden members at a joint. The gang nail plates come in different sizes and designs to suit various construction needs. Here are the common types:

• Standard plates

  These are the most common types. They are used in constructing roofs, floors, and bridges trusses. They come in different sizes to accommodate various wood dimensions. Also, they have varying thicknesses. The thickness ranges from 0.05 inches to 0.07 inches. Standard plates can be used in both softwood and hardwood applications.

• Heavy-duty plates

  These plates are also known as HD plates. They are designed for high-load applications. For instance, in the construction of industrial roofs and high-capacity storage. The plates are thicker than the standard ones, with a thickness of about 0.09 inches. They are made of high-strength steel, which has a tensile strength of about 450mpa.

• Galvanized plates

  These gang nail plates have a galvanized steel construction. The zinc coating allows them to resist corrosion and oxidation. Therefore, they are suitable for use in environments with high moisture content. They are commonly used in the construction of coastal and residential areas.

• Coated plates

  The plates are made of steel and have a coating of epoxy, powder, or polymer. The coating helps to improve their corrosion resistance. It also enhances their aesthetic appearance. Coated plates are suitable for use in exposed areas where style and functionality are required.

• Precut plates

  The plates are precut to specific sizes and shapes. This helps to enhance the convenience and speed of construction. They are suitable for prefabricated trusses and custom wood projects.

• Reinforced plates

  These plates are designed for specific applications. They have additional features like ribs, geometrical patterns, or reinforced webs. This improves their structural integrity. Also, it increases their load-carrying capacity. Reinforced plates are commonly used in the construction of high-rise buildings and large-scale structures.

Functions and features of gang nail_2

Gang nails, also known as truss plates, are used to connect timber members in roof and floor trusses. They provide structural integrity and stability to the construction. The plates are manufactured from steel and are sharp on one side and flat on the other side. Below are the features and functions of gang nails:

• Connection of timber

  Plates provide connection for timber in trusses. They ensure all the timber in the trusses are connected and support each other. Without the plates, the trusses would not be able to support the loads they carry.

• Load distribution

  The gang nails help to spread out the weight and pressure evenly across all the timber members. This is important to ensure no single timber member gets overloaded or damaged. Distributing the load helps to keep the trusses stable and intact.

• Joint reinforcement

  These plates reinforce the joints where timber members meet. The sharp points on the gang nail plates allow them to be easily driven into the timber. Once they are nailed, the plates hold the trusses together very tightly. This prevents the joints from moving or shifting, which could cause structural damage to the trusses.

• Shear transfer

  The plates allow for shear forces to be transferred between timber members. When the trusses receive a load, there are forces trying to slide the timber members past each other. The gang nails help to resist this sliding motion by transferring the shear force across the joint. This keeps the trusses from bending or breaking.

• Vertical and horizontal loads

  Gang nails connect vertical and horizontal timber members to form a strong frame. They ensure the vertical and horizontal pieces work together to support the entire structure. Whether the vertical or horizontal members, the plates make sure the loads are safely transferred and supported.

Scenarios of gang nail_2

Gang nails, also known as truss plates, are used in various structural applications. Here are some common scenarios:

• Roof Trusses

  Gang nails connect wooden roof trusses. The trusses create triangular support frameworks for pitched roofs in houses, garages, and other buildings. The plates evenly distribute the load across the wooden beams. This connection is vital for the structural integrity of the roof.

• Floor Trusses

  Floor trusses are similar to roof trusses. They support horizontal floor beams. Gang nails connect wooden beams in a truss system. The system supports the floor in residential and commercial buildings. With the help of these plates, the load is distributed evenly across the structural beams. This ensures the floor remains stable and safe.

• Wall Framing

  Truss plates are used in wall framing. They connect wooden beams (studs) in the wall structure. This forms a strong framework for load-bearing walls in houses and buildings. The gang nails allow the transfer of loads from the wall to the foundation of the building.

• Post and Beam Construction

  In post-and-beam setups, the gang nails join horizontal beams to vertical posts. This creates an open-concept structure seen in modern homes and commercial buildings. The plates enhance the structural integrity of the wooden frame. This allows for larger spaces without internal supports.

• Bridge Construction

  Gang nails are used in the construction of wooden pedestrian or vehicle bridges. They connect beams and trusses, forming a strong framework that can support the weight of pedestrians and vehicles. The plates ensure the bridge is stable and safe for use.

• Timber Frame Construction

  In timber frame construction, gang nails connect wooden beams and girts. This creates a strong frame for houses and other buildings. The plates enable the transfer of loads from the roof to the walls and the foundation. This ensures structural integrity.

How to Choose gang nail

Choosing the right gang nails for a specific project involves considering several factors to ensure structural integrity, cost-effectiveness and ease of construction. Here are some key factors to consider:

• Load-Bearing Capacity

  Consider the loads the truss will bear. This includes the weight of the roof or floor deck, beams, walls, snow loads and potential wind loads. Higher loads may require thicker, stronger gang nails. Consult an engineer to determine the best load-bearing gang nail for your needs.

• Truss Design

  The type of truss design will affect gang nail choice. For example, lookouts, queen posts and king post trusses distribute loads differently. Designs like Warren or Pratt trusses may allow for lighter gang nails. Choose nails that suit the truss geometry to ensure structural efficiency.

• Wood Thickness

  Consider the thickness of the timber components that the gang nail will connect. Manufacturers produce nails for different wood thicknesses. Ensure the chosen nail will adequately penetrate the timber for a strong connection. Nails must pass through thicker wood for stability.

• Environmental Conditions

  Consider the environmental conditions where the truss will be installed. If it will be exposed to moisture, use galvanized or treated gang nails to prevent rusting. Coastal areas may require stainless steel nails due to high salt exposure. Climate impacts material choices.

• Ease of Installation

  Some gang nails are easier to install than others. Consider the construction crew's experience and equipment. Larger nails may require more powerful pneumatic tools but provide quicker installation than smaller manual nails. Balance speed and skill requirements.

• Cost Considerations

  Price is always a factor when choosing materials. Larger, heavier gang nails will generally cost more than smaller ones. However, cheaper nails are no bargain if they compromise the truss's structural integrity. Consider the overall value, not just the purchase price of the nails.

• Availability

  Ensure the selected gang nails are readily available from local suppliers. Unique or specialty sizes may cause delays if not in stock. Planning ahead will keep construction on schedule.

• Aesthetic Considerations

  If the trusses will be exposed, the appearance of the gang nails matters. Look for options that provide a finished look, such as decorative plates or concealed fasteners. Work with the architect on aesthetic details.
