What is difference between Gross Coverage vs Net Coverage of PBR Panel?

PBR (Purlin Bearing Rib) panels are commonly used in the construction industry for roofing and wall applications. The terms "gross coverage" and "net coverage" refer to the amount of surface area that a PBR panel can effectively cover.

Gross coverage refers to the total area that a PBR panel can cover, including the overlap between adjacent panels. This measurement takes into account the entire width of the panel, including the overlapping rib, which is typically around 1.5 inches.

On the other hand, net coverage refers to the actual surface area that a PBR panel can cover without including the overlap. It is calculated by subtracting the overlap from the gross coverage. Net coverage is important to consider when determining the number of panels needed for a project and the cost of materials.

In general, gross coverage is used for estimating the total area of coverage needed, while net coverage is used for calculating the actual number of panels required for a project. It's important to take both gross and net coverage into account when planning a construction project using PBR panels to ensure that the correct amount of materials are ordered and that the installation is properly executed.

The Net Coverage on PBR Panels is 36 inches (3FT)

What is the difference between Galvalume and Galvanized steel?

Steel is one of the most commonly used materials in construction and manufacturing. However, not all steel is created equal. There are several types of steel, and each one has its unique properties and uses. Two popular types of steel that are commonly used in construction and manufacturing are Galvalume and Galvanized steel. Although they might seem similar, there are some significant differences between the two.

Galvanized steel is a type of steel that has been coated with a layer of zinc. This process, known as galvanization, is done to protect the steel from corrosion. The zinc coating creates a barrier between the steel and the surrounding environment, preventing rust and other forms of corrosion. Galvanized steel is often used in outdoor structures, such as fences, roofs, and gutters, as it can withstand harsh weather conditions.

Galvalume, on the other hand, is a type of steel that has been coated with a mixture of zinc, aluminum, and silicon. This coating provides better protection against corrosion compared to galvanized steel. Galvalume is also more durable and can withstand extreme weather conditions, making it a popular choice for roofing and siding.

One of the main differences between Galvalume and Galvanized steel is the composition of the coating. Galvanized steel has a pure zinc coating, while Galvalume has a mixture of zinc, aluminum, and silicon. This composition gives Galvalume better corrosion resistance and durability than Galvanized steel.

Another difference is the appearance. Galvanized steel has a shiny silver finish, while Galvalume has a matte gray finish. This difference in appearance is due to the composition of the coating. The aluminum and silicon in the Galvalume coating give it a duller appearance.

When it comes to cost, Galvanized steel is generally cheaper than Galvalume. However, Galvalume's superior corrosion resistance and durability make it a better long-term investment, especially for structures that will be exposed to harsh weather conditions.

In conclusion, Galvanized steel and Galvalume are two popular types of steel that are commonly used in construction and manufacturing. While they might seem similar, there are significant differences between the two. Galvalume has a better corrosion resistance and durability, but it is more expensive than Galvanized steel. When choosing between the two, it is essential to consider the specific application and the environmental conditions the steel will be exposed to.

4 Tips For Buying B-Deck

4 Tips For Buying B-Deck

Whether it’s your first-time buying B-Deck or you are a pro, here are some tips that will come in handy!

What is B-Deck?

B Deck is the most commonly used structural metal decking. It’s 1.5” deep and 36” wide and it’s available as a non-composite roof deck or a composite floor deck. B Deck is a non-composite roof deck only, meaning it is a smooth metal decking.

What can I use B-Deck for?

The B-Deck is the most popular and widely used decking panel in the market today. The Type B-Deck or Wide Rib can be used for several applications such as flooring, siding, and roofing. Metroll most commonly sells and stocks this material in the standard galvanized finish.

Interlock Or Nestable?

Interlock and nestable are two different types of deck designs used in the manufacturing of pallets, which are flat structures used to support goods during transport and storage.

Interlocking deck boards have a unique design that allows them to fit together like puzzle pieces. The edges of each board have a protruding feature that fits into a groove on the adjacent board. This interlocking design provides additional stability and strength to the pallet, making it ideal for heavy loads and rough terrain.

Nestable deck boards, on the other hand, are designed to nest inside each other when stacked. The edges of each board are slightly angled, allowing them to fit together and reduce the overall height of the pallet stack. This design is especially useful for saving space during transportation and storage.

The main difference between interlock and nestable deck designs is that interlocking decks provide more stability and strength, while nestable decks are better for saving space. The choice between the two designs depends on the specific needs and requirements of the application.

Swedge or Non Swedge

B-Deck is a type of corrugated metal decking used in construction for flooring or roofing applications. The two main types of B-deck are swedge and non-swedge.

Swedge B-Deck

Has a modified end that is designed to interlock with the next sheet of decking. The swedge end has a tapered edge that allows it to fit inside the next sheet of decking, creating a tight and secure connection between the two sheets. This design provides added stability to the decking system and eliminates the need for additional fasteners, reducing installation time and cost.

Non-swedge B-Deck

On the other hand, has a straight edge on both ends of the sheet. This design requires the use of additional fasteners to secure each sheet of decking to the structure. Non-swedge B-deck is typically used in applications where the decking will be overlapped and fastened together with screws or bolts.

The main difference between swedge and non-swedge B-Deck?

Is the way the sheets are connected. Swedge B-deck has a modified end that interlocks with the next sheet, providing added stability and eliminating the need for additional fasteners. Non-swedge B-deck has a straight edge on both ends and requires additional fasteners to secure each sheet to the structure.

When choosing between swedge and non-swedge B-Deck?

It is important to consider the specific needs and requirements of the application. Swedge B-deck may be more suitable for applications where fast installation and added stability are required, while non-swedge B-deck may be more suitable for applications where decking will be overlapped and fastened together with screws or bolts.

Floor Embossed or Roof Smooth

B-deck is a type of corrugated metal decking used in construction for flooring or roofing applications. The two main types of B-deck are floor embossed and roof smooth.

Floor Embossed B-Deck

Has raised bumps or embossments on the top surface of the deck. This design provides better traction for foot traffic and equipment, making it ideal for flooring applications. The embossments also help to increase the structural integrity of the deck, making it better suited for heavy loads and high traffic areas.

Roof Smooth B-Deck

On the other hand, has a smooth surface on both the top and bottom of the deck. This design makes it ideal for roofing applications, where a smooth surface is needed for the attachment of roofing materials. The smooth surface also makes it easier to clean and maintain the roof.

The main difference between floor embossed and roof smooth B-Deck ?

Is the surface texture. Floor embossed B-deck has raised embossments on the top surface for better traction and structural integrity, while roof smooth B-deck has a smooth surface on both sides for easier attachment of roofing materials and maintenance.

When choosing between the two types of B-Deck

It is important to consider the specific needs and requirements of the application. For example, if the deck will be used for flooring in a high traffic area, floor embossed B-deck may be the better choice. If it will be used for roofing, roof smooth B-deck may be the more suitable option.
