The manual offers in-depth chapters on the properties and design of traditional and modern formwork materials, including wood, plywood, aluminum, steel, and even plastics. Given that wood remains the most common material for many formwork components, SP-4 provides extensive design tables and specific values updated to reflect the latest National Design Specification® (NDS) standards from the American Wood Council.
