High-quality original factory supply SCW490 Heavy Duty Corner Castings

The RD-CC-01 and Model 218 corner castings are engineered for container handling, modular construction, and logistics. Made of SCW490 cast steel with precise dimensions. They are not generic metal blocks – they are ISO 1161-compliant structural components.

User Problem: Unstable container stacking, lifting failure, corrosion or cracking of corner castings – leading to cargo damage or safety incidents.
Cause Explanation:

· Low-grade materials (e.g., grey iron) with insufficient strength
· Excessive dimensional tolerance, mismatch with twist locks
· No anti-corrosion treatment, rapid rusting in humid/saline environments

The RD-CC-01 and Model 218 corner castings offer a material + precision + corrosion resistance solution:

· SCW490 weldable structural steel, yield strength ≥295MPa
· Dimensions 178×162×118mm (RD-CC-01) or 218×162×118mm (Model 218) – standard twist lock fit
· Surface options: none, coating, or hot-dip galvanized (HDG) for indoor/outdoor use

Conclusion: Right corner casting = safe stacking + longer service life.

How It Works(工作原理)

中文
角件是集装箱八个角部的关键受力节点:

· 堆叠时:上层角件下孔与下层角件上孔对齐,旋锁锁紧,传递垂直载荷
· 起吊时:吊具旋锁插入角件侧孔,起吊力通过角件均匀传递至整个箱体
· SCW490材料提供抗冲击和抗疲劳性能,防止断裂

English
Corner castings are the key load-bearing nodes at the eight corners of a container:

· Stacking: Bottom hole of upper casting aligns with top hole of lower casting; twist lock secures and transfers vertical load
· Lifting: Spreader twist locks insert into side holes; lifting force distributes evenly through the casting
· SCW490 provides impact and fatigue resistance, preventing fracture

How To Choose(选型指南)

中文

需求场景 推荐型号 表面处理
标准20/40尺海运集装箱 RD-CC-01 (178mm长) 热镀锌 HDG
宽体模块或特殊框架 218型 (218mm长) 涂层或热镀锌
室内短期使用 RD-CC-01 无处理或涂层
高盐雾环境(码头,沿海) 任一型号 必须热镀锌 HDG
焊接维修替换 与原箱匹配尺寸 与原箱一致

选型结论:先确认原角件长度(178或218mm),再根据使用环境决定表面处理.

English

Requirement Recommended model Surface
Standard 20/40ft marine container RD-CC-01 (178mm length) HDG
Wide modular or special frames Model 218 (218mm length) Coating or HDG
Indoor short-term use RD-CC-01 None or coating
High salinity (ports, coastal) Either HDG mandatory
Welding replacement Match original length Match original

Selection conclusion: First confirm the original corner casting length (178 or 218mm), then choose surface treatment based on environment.

FAQ(常见问题)

1. RD-CC-01和218型角件可以互换吗?
中文:不可以.长度不同(178 vs 218mm),锁孔位置变化会导致无法对齐标准集装箱角件.必须按原设计尺寸选择.
English: No. Different lengths change hole positions; will not align with standard container castings. Always match original dimension.

2. 热镀锌(HDG)比涂层贵多少?使用寿命多长?
中文:热镀锌成本约高20-30%,但在室外环境下寿命可达15-20年；普通涂层2-3年即出现锈斑.
English: HDG costs ~20-30% more, but lasts 15-20 years outdoors; standard coating shows rust within 2-3 years.

3. SCW490材料相当于什么国内牌号?
中文:SCW490是日标焊接结构用铸钢,接近国标ZG230-450或ZG270-500,但焊接性能更好.
English: SCW490 is JIS cast steel for welded structures; similar to GB ZG230-450 or ZG270-500 but with better weldability.

4. 单件包装尺寸就是产品本身尺寸吗?如何运输?
中文:是,单件无包装时即为净尺寸.通常采用托盘或木箱散装运输,避免碰撞变形.
English: Yes, it‘s the net dimension without packaging. Usually shipped in bulk on pallets or in wooden crates to avoid impact damage.

5. 这些角件是否有CE或ISO证书?
中文:可按客户要求提供材料测试报告及尺寸检验记录,符合ISO 1161标准.
English: Material test reports and dimensional inspection records available upon request, compliant with ISO 1161.
