s420m Steel

Gnee® Steel offers 4 grades of S420m-certified alloy steel plate. Available supply shapes such as plates, profiles, bars, coils and tubes.

S420M is a high-strength, low-alloy structural steel that falls under the EN 10025-4 standard. The “S” in S420M stands for structural steel, and the “M” indicates that it is thermomechanically rolled. S420M steel offers excellent mechanical properties and good toughness, suitable for various construction and engineering applications.

Plates – Most commonly used shape. Supplied in thicknesses ranging from 0.2mm to 200mm, widths up to 3.5m and lengths up to 18m. Used for building construction, pressure vessels,storage tanks,aumobile industry etc.
Coil – a finished steel product such as sheet or strip which has been wound or coiled after rolling. Mainly used for pipe-manufacturing, structural steel members, electronic components, automotive parts.
Tubes – There are two types of round steel pipes and square steel pipes. Widely used in construction, industrial applications, the medical industry, and to manufacture automobiles.
Bars – Also known as steel rods or steel round bars, are long, solid cylindrical bars made primarily of steel. They are used in agriculture, oil and gas, tool and die, defense, rail, and power generation industries.
Chequered plate – is a type of steel plate with a raised pattern of raised diamonds or lines on its surface. Due to Excellent anti-slip properties, it mainly used for industrial flooring, stair treads, ramps, and walkways.
Other shapes – S420M can also be customized into half-rounds, flat bars, beam sections etc. based on requirements.

Gnee提供哪些服務?

Gnee can provide the following measurement services for ABS Steel:

1. 尺寸測量:透過測量儀器測量長度、寬度、厚度等尺寸參數,確保鋼板合格,符合設計要求。
2. 表面測量:測量鋼板表面的平整度、不平整度、表面粗糙度等參數,有助於確保鋼板的品質和表面狀態符合要求。
3. 厚度測量:使用測厚儀準確測量鋼板厚度,確保符合設計要求。
4. 材料測量:利用材料分析儀器測量鋼板的化學成分和機械性質,確保鋼板的品質和性能符合要求。
5. 彎曲和變形測量:在造船過程中,鋼板可能會彎曲和變形。利用彎曲測量儀、位移感測器等工具對鋼板的彎曲變形程度進行測量和監控,確保其在允許範圍內。

詢問測量服務

Gnee可以根據您的特定專案需求,為您的海洋專案訂製鋼板的尺寸和形狀。鋼板的客製化設計由專業的工程師和設計團隊進行。他們將根據專案的要求和約束,使用計算和模擬工具,結合經驗和技術知識,優化鋼板設計,以滿足您的海洋工程的特定需求。

● 依照結構設計的荷載計算和強度需求,調整造船鋼板的厚度、寬度和長度
● 鋼板形狀可依海洋環境特性設計。例如,為了減少波浪對結構的影響,鋼板的形狀可以是球形或扁平形。
● 如果考慮安裝和維護的方便性,對於需要經常維護的區域,我們還可以在設計中增加開口和通道,以便於進出和操作。
