Materials used for forms for concrete include lumber, plywood, hardboard, fiberglass, plastics and rubber liners, steel, paper and cardboard, aluminum, fiber forms, and plaster of paris. Additional materials include nails, bolts, screws, form ties, form clamps, anchors, various, types of inserts, and various types of form oils and compounds as well as their accessories. Forms frequently involve the use of two or more materals, such as plywood facing attached to steel frames for wall panels.
Form lumber generally consisits of the softwoods with species used being the type available in the local area. Various species are usually ground together for grading and marketing purposes. Some of these groups and their included species commonly used for formwork are:
1. Doughlas fir-larch(Douglas fir, western larch)
2. Douglas fir-South(only Douglas fir from southern growth areas)
3. Hem-fir(Western hemlock, California red fir, grand fir, noble fir, white fir, Pacific silver fir)
4. Spruce-pine-fir(alpine fir, balsam fir, black spruce, Englemann spruce, jack pine, lodgepole pine, red spruce, white spruce)
5. Southern pine(loblolly pine, longleaf pine, shortleaf pine, slash pine)
Form lumber is made up of standard sizes, either rough or dressed, with the grading quality of construction grade or No.2 grade usually speciafied. Shoring or falsework requiring greater capacity should be of seclct structural grade lumber. Partially seasoned wood should be used becaused it has been found to be found to be the most stable. Green lumber will warp and crack, wheras kiln-dried lumber will swell excessively when it becomes wet. Boards of various thicknesses may be used for sheathing when the imprint of the boards on the concrete surface surface is desired for architectural reasons.

3. 模板建设物料及设备
用于混凝土模板的材料包括木材,胶合板,硬质纤维板,玻璃纤维,塑料和橡胶衬里,钢铁,纸和纸板,铝,纤维模板,和熟石膏。附加材料包括钉,螺栓,螺钉,模板连接件,模板夹具,锚,等各种类型加插物件,以及各种类型模板用油和化合物,以及它们的配件。模板经常涉及使用两种或多种材料,比如胶合板面常与钢架连接用以墙板建设。

模板的木材一般是由当地常见树种的软木所组成。不同品种木材通常放在一起方便分级和营销。其中一些常用於模板建设的树木种类及其树种有:

1,花旗松-落叶松类(花旗松,西部落叶松)
2,南部花旗松类 - (只包括从南部地区生长的花旗松)
3,铁杉类(西部铁杉,加州红杉,巨杉,杉木高贵,白色冷杉,太平洋银冷杉)
4,云杉 - 松木 - 冷杉类(高山冷杉,香脂冷杉,黑云杉,英格曼云杉,短叶松,红松,红皮云杉,白云杉)
5,南方松类(火炬松,长叶松,短叶马尾松,湿地松)

模板木材是由标准尺寸,不论是粗糙或光滑,建筑级或第二级通常规定等级质量的木材构成。撑或临时支架需要的用量更大,因此需要严选同等级的木材。应该采用局部风干的木材,因为它们的材质已被证实是最稳定的。而新湿木材易变形和开裂,烘干的木材则变湿时会容易过度膨胀。不同厚度的木板会用作护套,但只有板面印记显出在混凝土表面的是合符建筑目的所需的
