The lateral and end overlap of the color steel plate. When installing each steel plate, its edges should be accurately overlapped and placed on the previous colored steel plate, and clamped with the previous steel plate until both ends of the steel plate are fixed. A simple and effective method is to use a pair of pliers to clamp the overlapping steel plates separately. When the steel plate is positioned longitudinally, its end, especially the upper end, needs to be clamped with pliers to ensure that one end of the steel plate is in place and the overlap at one end is also in the correct position, thereby fixing the steel plate. During the fixation process, the pliers should always clamp the steel plate longitudinally. Before installing the next steel plate, each steel plate must be completely fixed. Fixation must start at the center of the steel plate, then extend to both sides, and finally fix the overlapping edge of the steel plate. For end lap joints, as the roof and wall exterior panels are made using continuous processing methods, steel plates can be supplied according to the length limited by transportation conditions. Usually, lap joints are not required, and the length of the steel plates is sufficient to meet the needs of roof laying.

自攻螺釘的選用。固定螺釘選用時應該按照結構的使用壽命選擇固定件，而且特別注意外覆材料的壽命與指定的固定件壽命是否一致。同時注意鋼檁條厚度不能超過螺釘的自鉆能力。目前供應的螺絲可帶有塑料頭、不銹鋼頂蓋或涂有特殊的耐久保護層。另外，除暗扣固定用螺釘外，其他螺釘均帶有防水墊圈，而且針對采光板和特殊風壓下的情況均配有相應的專用墊圈。

Selection of self tapping screws. When selecting fixing screws, the selection of fixing components should be based on the service life of the structure, and special attention should be paid to whether the service life of the outer covering material is consistent with the specified service life of the fixing components. At the same time, it should be noted that the thickness of the steel purlin should not exceed the self drilling capacity of the screw. The screws currently supplied can come with plastic heads, stainless steel caps, or coated with a special durable protective layer. In addition, except for the screws used for fastening with concealed buckles, all other screws are equipped with waterproof washers, and corresponding special washers are provided for lighting boards and special wind pressure situations.

彩鋼板的安裝較易掌握，而一些細節(jié)的處理比較重要。對于屋面用彩鋼板應該在屋頂及屋檐處將彩鋼板進行相應的收邊工作，其目的是為了更有效地阻止雨水進入屋面以內。屋面外板在屋脊的地方，都可用收邊工具將位于鋼板終端肋條之間的底盤向上折。它用于所有坡度低于1/2(250)屋面鋼板的上端，以保證在泛水板或蓋板下方由風吹入的水不會流入建筑之中。

The installation of color steel plates is easier to master, and the handling of some details is more important. For the color steel plate used on the roof, corresponding edge trimming work should be carried out on the roof and eaves, in order to more effectively prevent rainwater from entering the roof. At the ridge of the roof, the outer panel of the roof can be folded up using edge closing tools to fold the chassis between the steel plate end ribs. It is used at the upper end of all roof steel plates with a slope below 1/2 (250) to ensure that water blown in by the wind under the flashing or cover plate does not flow into the building.

在南方彩鋼板一般設計為單層彩鋼板，為了減少太陽輻射熱量進入建筑物內部，在安裝屋面板時，可以在屋面系統(tǒng)中裝入隔熱層。有一種非常簡單、經濟而有效的方法，即在安裝屋面鋼板之前，在檁條或板條上鋪上雙面反射箔薄膜，這種方法同樣還可以作為蒸汽隔離，以減少凝聚作用。

In southern China, color steel plates are generally designed as single-layer color steel plates. In order to reduce the entry of solar radiation heat into the interior of buildings, insulation layers can be installed in the roof system when installing roof panels. A very simple, economical and effective method is to lay a double-sided reflective foil film on the purlin or Flat noodles before installing the roof steel plate. This method can also be used as steam isolation to reduce condensation.
