木材以类似的方式进行了调查。综述了木材的结构以及木材的不同性质。软木和硬木之间的主要差异进行记录。木材的水分对木材的影响进行了讨论，以及木材的脆弱性，以真菌和昆虫的攻击，而在服务被视为。 钢同样调查。简要回顾了钢的结构，没有深入研究冶金学。合金元素对钢的性能有很大的影响，并讨论了这些因素对钢性能的影响。讨论了钢的强度特性，最后讨论了钢材锈蚀的趋势，特别是在我国这样的气候下。 一旦三个材料充分理解，他们比较为框架材料。五个性能标准作为比较的基础是安全性，耐用性，成本，速度和可持续性，以重要性的顺序。要显示的重要性的影响，每个标准被赋予的重量，然后乘以每个材料的性能。材料的最大加权性能值的总和是最好的材料。钢被证明是最好的无可争议的保证金。然而，必须强调的是，价值本身并没有多大用处。这仅仅是定性分析和结论得出的反映.

Timber was investigated in a similar fashion. The structure of wood as well as the different properties of wood was reviewed. The main differences between softwood and hardwood were documented. The effect of moisture on wood was discussed as well as the vulnerability of timber to fungal and insect attacks while in service were looked at.
Steel was investigated similarly. The structure of steel was reviewed briefly, without going into deep details of metallurgy. The properties of steel are greatly influenced by alloying elements and the effects of those were discussed. The strength characteristics of steel were discussed and finally the tendency of steel to rust, especially in a climate like ours was discussed.
Once the three materials were understood sufficiently, they were compared as framing materials. The five performance criteria used as a basis of comparison were safety, durability, cost, speed and sustainability, in order of importance. To show the effect of importance, each criterion was given a weight, which was then multiplied by the performance of each material. The material with the maximum total of weighted performance values was the best material. Steel proved to be the best by an undisputed margin. However, it has to be stressed that the value in itself is not of much use. It is merely a reflection of the qualitative analysis and conclusions drawn
