大多数人都知道铝有出色的强度重量比，例如，梯形电缆托盘的宽度为36英寸、长度为24英尺、侧面轨道为6英寸的NEMA20C热镀锌钢制电缆托盘的重量约为200磅，铝的相同电缆托盘的重量约为100磅。当安装人员需要提起电缆托架部分并将其放置在离地面30英尺或30英尺以上的地方时，铝的重量较轻意味着只需要两个安装人员，而不是四个安装人员。

Most people know that aluminum has an excellent strength to weight ratio. For example, a NEMA20C hot-dip galvanized steel cable tray with a width of 36 inches, a length of 24 feet, and a side track of 6 inches weighs about 200 pounds, while an aluminum cable tray of the same weight weighs about 100 pounds. When installers need to lift the cable tray section and place it 30 feet or more above the ground, the lightweight of aluminum means only two installers are needed instead of four.

铝电缆托盘也更容易进行现场切割，因为铝容易切割、穿孔、容易打孔，不需要在外面的边缘涂保护层。钢的热镀锌涂层建议用比原来镀锌逊色的富锌涂料(也称为冷镀锌)进行维修。这样可以在钢的手套上留下缝隙，防止腐蚀。当然总有承包商完全不修理可能进一步损害电缆托盘耐蚀性的切口。

Aluminum cable trays are also easier to cut on site because aluminum is easy to cut, pierce, and drill, and does not require a protective layer on the outer edges. The hot-dip galvanized coating on steel must be repaired with a zinc rich coating (also known as cold galvanizing) that is inferior to the original galvanizing. This can leave gaps on the steel gloves to prevent corrosion. Of course, there are always contractors who do not repair any cuts that may further damage the corrosion resistance of the cable tray.

铝电缆托盘组件是挤压的，因此热浸锌桥架厂家认为可以更有效地利用材料，公差也更小。一些制造商建立接合接合和其他功能，为承包商提供更好的效能，减少安装工作，以用于承包商的优点。此外，当电缆托盘用作设备接地导体(EGC)时，铝出色的载流能力减少了购买和安装单独的EGC(合格工业安装中)的需要，并提供了更好的故障电流路径，从而提高了安装安全性。

Aluminum cable tray components are extruded, so hot-dip galvanized cable tray manufacturers believe that they can more effectively utilize materials and have smaller tolerances. Some manufacturers establish joints and other functions to provide better efficiency for contractors, reduce installation work, and benefit contractors. In addition, when cable trays are used as equipment grounding conductors (EGCs), the excellent current carrying capacity of aluminum reduces the need to purchase and install separate EGCs (in qualified industrial installations), and provides a better fault current path, thereby improving installation safety.

热浸锌桥架厂家说说交付和可用性

Hot dip galvanized bridge manufacturer discusses delivery and availability

铝电缆托盘系统一般可在短时间内从工厂装运，根据制造商的工作量，小订单可以在几天内发送。热镀锌电缆托盘系统通常需要几天的制造、镀锌和准备配送。

Aluminum cable tray systems can generally be shipped from the factory in a short period of time, and small orders can be sent within a few days depending on the manufacturer's workload. Hot dip galvanized cable tray systems typically require several days of manufacturing, galvanizing, and preparation for distribution.

所有电缆托盘制造商建议将电缆托盘运送给第三方进行镀锌处理，为此热浸锌桥架厂家认为，需要制造和包装电缆托盘，用镀锌机运输。一些制造商为了在包装和装运前检查和违背产品，在镀锌后将材料送回工厂。其他热浸锌桥架厂家依靠热针镀锌机检查去除毛刺，包装要运输的材料。

All cable tray manufacturers must transport cable trays to third parties for galvanizing treatment. Therefore, hot-dip galvanized cable tray manufacturers believe that cable trays need to be manufactured and packaged for transportation using galvanizing machines. Some manufacturers send materials back to the factory after galvanization in order to inspect and violate products before packaging and shipping. Other hot-dip galvanized bridge manufacturers rely on hot-dip galvanizing machines to inspect and remove burrs, and package the materials to be transported.

将材料发送到现场的成本是材料本身成本的数倍，使用铝电缆托盘可以较大限度地减少延迟的可能性。热镀锌钢制电缆托盘盖带来了另一个问题，如果将薄规格的钢套放在热锌浴中，盖子经常变形。为了避免此问题，请使用厚材料，盖子长度不应超过6英尺。安装短外罩所需的额外材料和额外劳动力对整个电缆桥架系统的成本有很大影响。

The cost of sending materials to the site is several times the cost of the materials themselves, and using aluminum cable trays can greatly reduce the possibility of delays. The hot-dip galvanized steel cable tray cover brings another problem, if a thin specification steel sleeve is placed in a hot zinc bath, the cover often deforms. To avoid this issue, please use thick materials and the length of the lid should not exceed 6 feet. The additional materials and labor required for installing short enclosures have a significant impact on the cost of the entire cable tray system.
