圍擋批發(fā)需要注意哪些事項(xiàng)

來源:http://www.btmj.net/   發(fā)布時(shí)間:2022-09-20

在工程施工過程中都需要用到圍擋,小區(qū)隔離封閉也需要用到圍擋,市政建設(shè)也需要用到圍擋,由此可見濟(jì)南圍擋的市場需求量還是十分巨大的,施工單位需要經(jīng)常用到面臨圍擋批發(fā)采購工作,那么在圍擋批發(fā)過程中要注意哪些方面的問題呢?
Fences are required in the construction process, the isolation and closure of residential areas, and municipal construction. It can be seen that the market demand for fencing in Jinan is still huge, and the construction unit often needs to use it to face the wholesale procurement of fencing. What problems should be paid attention to in the process of fencing and wholesale?
1、檢測。結(jié)合第三方機(jī)構(gòu)進(jìn)行檢測或者要求廠家提供檢測文件,正規(guī)的PVC圍擋廠家都會有《pvc圍擋檢驗(yàn)報(bào)告》,并獲得質(zhì)量管理體系《ISO9001:2000》的認(rèn)證。
1. Professional testing. In combination with the testing conducted by a third-party organization or the manufacturer is required to provide testing documents, regular PVC enclosure manufacturers will have a PVC Enclosure Inspection Report and obtain the certification of the quality management system ISO9001:2000.
2、PVC圍擋質(zhì)量的優(yōu)劣,關(guān)鍵看板材,區(qū)分板材質(zhì)量的優(yōu)劣可以從切口位置,用手掰,看變形程度越,正常的pvc板厚一般都在0.7、0.8公分以上,這個跟原材樹脂粉適用的比例有關(guān)系。
2. The quality of PVC enclosure depends on the quality of the board. The quality of the board can be distinguished from the position of the cut by hand. The more the deformation is, the normal thickness of the PVC board is generally more than 0.7 cm or 0.8 cm, which is related to the proportion of raw material resin powder.

3、圍擋施工完畢,看一下板與板之間銜接是否平順,直線是不是在一條直線上;要求板與板不得留有縫隙,即在場外不能看見場內(nèi)施工,圍擋沿線設(shè)置紅燈或者隔段用反光錐用于夜間警示。
3. After the construction of enclosure, check whether the connection between plates is smooth and whether the straight line is in a straight line; It is required that there shall be no gap between boards, that is, no construction can be seen outside the site. Red lights are set along the fence or safety reflective cones are used for warning at night.
4、安裝過程中??窗宓念伾欠褚恢拢繖n十塊板,合格的pvc圍擋顏色、亮度及質(zhì)感都是一致的,如果顏色上有差別,那么很大程度上是用回收料做的。
4. During installation. Whether the color of the signage is consistent. The color, brightness and texture of the qualified PVC enclosure are consistent for ten boards in each file. If the color is different, it is largely made of recycled materials.
所以施工單位在選購PVC圍擋的時(shí)候,不能只關(guān)注低價(jià),一分錢一分貨,廠家不會做虧本的買賣。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.btmj.net進(jìn)行咨詢吧!
Therefore, when purchasing PVC enclosures, the construction unit should not only pay attention to the low price, and the manufacturer will not make a loss. More relevant content will come to our website http://www.btmj.net Consult!
