Wrought formwork is created by bending and shaping metal sheets or rods into the desired formwork shape, often using heat and mechanical force. Sawn formwork, on the other hand, is fabricated by cutting and shaping wooden boards or panels to the required dimensions for formwork construction. Wrought formwork is typically more durable and reusable than sawn formwork, but it is also generally more expensive and requires specialized equipment for fabrication. Saw formwork is more commonly used for temporary formwork applications due to its lower cost and ease of construction.

What is the sawN formwork?
Sawn formwork is formwork that for concrete structure that needs to have plaster and paint finish.
What are the differences between rift sawn and plain sawn wood, and how do these differences impact the quality and appearance of the final product?
Rift sawn wood is cut at a different angle than plain sawn wood, resulting in a more stable and straight grain pattern. This makes rift sawn wood less prone to warping and shrinking. In contrast, plain sawn wood has a more varied grain pattern and is more likely to expand and contract with changes in humidity. The differences in grain pattern between rift sawn and plain sawn wood can impact the overall appearance and quality of the final product, with rift sawn wood often being preferred for its more uniform and refined look.
What are the differences between flat sawn and plain sawn wood, and how do these differences impact the quality and characteristics of the final product?
Flat sawn wood is cut parallel to the growth rings of the tree, resulting in a more prominent grain pattern and potential for warping. Plain sawn wood is cut perpendicular to the growth rings, producing a more uniform appearance and greater stability. These differences impact the final product by affecting its strength, appearance, and resistance to warping or shrinking. Overall, plain sawn wood is often considered higher quality due to its stability and consistent appearance.
What are the differences between flat sawn and rift sawn wood, and how do these differences impact the quality and characteristics of the final product?
Flat sawn wood is cut parallel to the growth rings of the tree, resulting in a more prominent grain pattern and potential for warping. Rift sawn wood is cut at a different angle, producing a straight grain pattern and greater stability. The differences impact the appearance, strength, and durability of the final product, with rift sawn wood generally being more desirable for high-quality furniture and flooring due to its superior stability and resistance to warping.
What are the differences between plain sawn and quarter sawn wood, and how do these differences impact the quality and appearance of the final product?
Plain sawn wood is cut parallel to the growth rings of the tree, resulting in a varied grain pattern. Quarter sawn wood is cut perpendicular to the growth rings, creating a straight grain pattern. Quarter sawn wood is more stable and less prone to warping, making it higher quality for certain applications. It also has a distinctive appearance with ray flecks, while plain sawn wood has a more traditional grain pattern.
What are the differences between rift and plain sawn wood, and how do these differences affect the appearance and quality of the final product?
Rift sawn wood is cut at a different angle than plain sawn wood, resulting in a different grain pattern. Rift sawn wood has a straight grain pattern, while plain sawn wood has a more varied grain pattern. This difference affects the appearance of the final product, with rift sawn wood having a more uniform and consistent look. In terms of quality, rift sawn wood is less prone to warping and shrinking compared to plain sawn wood, making it a more stable option for certain applications.
What are the differences between plain sawn and rift sawn wood?
Plain sawn wood is cut parallel to the growth rings of the tree, resulting in a varied grain pattern with prominent cathedrals. Rift sawn wood is cut at a different angle, producing a straight grain pattern with minimal figure. This difference in cutting methods affects the appearance and stability of the wood.
What are the differences between flat sawn and quarter sawn wood, and how do these differences impact the quality and characteristics of the final product?
Flat sawn wood is cut parallel to the growth rings of the tree, resulting in a more traditional appearance with visible grain patterns. Quarter sawn wood is cut perpendicular to the growth rings, creating a straight grain pattern and greater stability. Quarter sawn wood is less prone to warping and shrinking, making it more durable and ideal for furniture and flooring. It also has a distinctive ray fleck pattern that some find visually appealing.
What are the differences between quarter sawn and flat sawn wood, and how do these differences impact the quality and characteristics of the wood?
Quarter sawn wood is cut perpendicular to the growth rings of the tree, resulting in a straight grain pattern and increased stability. This method also highlights the wood's medullary rays, giving it a distinctive appearance. On the other hand, flat sawn wood is cut parallel to the growth rings, producing a varied grain pattern and potentially more susceptibility to warping or cupping. Quarter sawn wood is generally considered higher quality and more durable than flat sawn wood due to its stability and unique appearance.
What are the differences between quarter sawn and plain sawn wood, and how do these differences affect the quality and appearance of the final product?
Quarter sawn wood is cut in a way that the growth rings are perpendicular to the surface, resulting in a straight grain pattern and increased stability. This method is more labor-intensive and produces less yield, but the wood is less prone to warping and shrinking. Plain sawn wood is cut parallel to the growth rings, resulting in a varied grain pattern and higher yield. However, this method can lead to more movement and distortion in the wood. Quarter sawn wood is often preferred for its durability and distinctive appearance, while plain sawn wood is more cost-effective but may require more maintenance to prevent warping.
What are the differences in appearance and stability between rift and quartered vs plain sawn wood?
Rift and quartered wood have a more consistent appearance with straight grain patterns, while plain sawn wood has a more varied appearance with cathedral-like grain patterns. In terms of stability, rift and quartered wood are less prone to warping and shrinking compared to plain sawn wood.
What are the differences between plain sliced and quarter sawn wood, and how do these differences impact the quality and characteristics of the final product?
Plain sliced wood is cut parallel to the growth rings of the tree, resulting in a varied grain pattern. Quarter sawn wood is cut perpendicular to the growth rings, creating a straight grain pattern. Quarter sawn wood is more stable and less prone to warping, making it ideal for furniture and flooring. It also has a distinctive appearance with ray flecks. Plain sliced wood is more common and less expensive, but may be less stable and prone to warping.
