Structural hollow sections of weathering steel

耐候钢结构空心型材

This EAD covers structural hollow sections made of structural steel with improved atmospheric corrosion resistance, hereinafter referred to as "hollow sections of weathering steel"

上海郜盟提示本EAD涵盖由具有改进大气腐蚀抗性的结构钢制成的结构空心型材，下文简称“耐候钢空心型材”

Hollow sections of weathering steel are not fully covered by the following harmonised technical specification: EN 10210-11. EN 10210-1 covers structural hollow sections of non-alloy and fine grain steels but the chemical compositions of those steels differ from the compositions of hollow sections of weathering steel. The grade designations are specific to hollow sections of weathering steel and are not contained in EN 10210-1. The methods of assessment, essential characteristics (other than the chemical composition)and factory production control measures in EN 10210-1 apply to the product, subject to the minor updates and clarifications of EN 10210-3.

耐候钢的空心截面未完全涵盖于以下统一技术规范:EN10210-11。EN10210-1涵盖非合金钢和细晶粒钢的结构空心截面，但这些钢材的化学成分与耐候钢空心截面的化学成分不同。等级标识专门针对耐候钢空心截面，且未包含在EN10210-1中。EN10210-1中的评估方法、基本特性(除化学成分外)及工厂生产控制措施适用于该产品，但需遵循EN10210-3的轻微更新和澄清。

The essential characteristic "reaction to fire" has been added to this EAD.

本EAD已新增“耐火性”这一基本特性。

Hollow sections of weathering steel are covered by EN 10210-3, which is not a harmonised standard and also covers other products. Table E.1 of EN 10210-3 specifies that the weathering steels must contain minimum amounts of chromium (Cr), copper (Cu) and at least one of aluminium (Al), niobium (Nb),vanadium (V and titanium (Ti). This composition distinguishes weathering steels from steels covered by EN 10210-1.

耐候钢的空心截面由EEN10210-3标准涵盖，该标准并非协调标准，同时也涵盖其他产品。EN10210-3的表E.1规定，耐候钢必须含有最低含量的铬(Cr)、铜(Cu)，以及铝(Al)、(Nb)、钒(V)和钛(Ti)中的至少一种。这种成分使耐候钢与EN10210-1所涵盖的钢材区别开来。

Hollow sections of weathering steel contain no organic material

耐候钢空心型材不含有机材料

The names for hollow sections of weathering steel are allocated in accordance with EN 10027-1. This EAD covers hollow sections of the following grades as defined in Annex E of EN 10210-3:

耐候钢空心型材的名称依据EN10027-1标准分配。本EAD涵盖EN10210-3附录E中定义的以下等级的空心型材:

-S355J0WH,

-S355J2WH

-S355K2WH

-S420K2WH,

-S460K2WH

-S500K2WH.

The use of these grade designations in Table E.3 of EN 10210- 3 implies that the grades referred to by this EAD are associated with a set of threshold values for yield strength Re, tensile strength Rm, elongation after fracture A and impact energy KV2. These values are established in the harmonised standard EN 10025-1 by reference to EN 10025-5 for grades of hot rolled products with improved atmospheric corrosion resistance that are equivalent to the grades referred to by this EAD. Products with performance outside Table E.3 of EN 10210-3 are not covered by this EAD.

EN10210-3中表E.3所使用的这些等级标识意味着，本EAD所提及的等级与一组屈服强度ReH抗拉强度Rm、断裂后伸长率A和冲击能量KV2的阈值相关联。这些数值在协调标准EN10025-1中确立，并参照EN10025-5，适用于具有改善的大气腐蚀性能且与本EAD所提及等级等效的热轧产品等级。性能超出EN10210-3表E.3范围的产品不在本EAD涵盖范围内。

The meaning of the grade designations for weathering steel is given in Clause 4.2.2 of EN 10210-3. The chemical composition of the weathering steel shall be in accordance with the composition for the specified grade given in Table E.1 of EN 10210-3. Any deviations in the chemical composition of the weathering steel shall be within the limits given in Table 1 of EN 10210-3.

耐候钢牌号的意义在EN10210-3第4.2.2条中规定。耐候钢的化学成分应符合EN10210-3表E.1中规定的指定牌号的成分。耐候钢化学成分的任何偏差应在EN10210-3表1规定的限度内。

A range of shapes and sizes of structural hollow sections is given in Clause 1 of EN 10210-2. Dimensional tolerances for these sections are given in Clause 6 of EN 10210-2. For consistency, the scope of this EAD is limited to a range of hollow sections of weathering steel of the same shapes, sizes and dimensional tolerances as EN 10210-2.

EN10210-2第1条规定了结构空心截面的多种形状和尺寸。这些截面的尺寸公差在EN10210-2第6条中给出。为保持一致性，本EAD的范围仅限于与EN10210-2具有相同形状、尺寸和尺寸公差的耐候钢空心截面。

Following Clause 1 (Scope) of EN 10210-3 the products are weather resistant hot finished seamless electric welded or submerged arc welded steel structural hollow sections of circular, square, rectangular or elliptical form.

根据EN10210-3第1条(范围)，产品为耐候性热加工无缝、电焊或埋弧焊接的钢结构空

心截面，形状为圆形、方形、矩形或椭圆形。

Weathering steel products are manufactured from high strength low alloy steel grades that, under normal atmospheric conditions, give an enhanced resistance to rusting. All low alloy steels tend to rust in the presence of moisture and air, whereby the rate of rusting depends on the access of oxygen, moisture and atmospheric contaminants to the metal surface. As rusting progresses, the rust layer forms a barrier to the ingress of oxygen, moisture and contaminants, and the rate of rusting slows down.
耐候钢产品由高强度低合金钢等级制成，在正常大气条件下具有更强的抗锈蚀能力。所有低合金钢在潮湿和空气存在下都会生锈，其生锈速率取决于氧气、水分和大气污染物对金属表面的接触程度。随着锈蚀的进展，锈层会形成一层屏障，阻碍氧气、水分和污染物的侵入，从而使生锈速

率减慢。

The rust layers formed on structural steels without an enhanced resistance are porous and detach from the metal surface after a certain time, and the corrosion cycle commences again. Consequenty, the rusting rate progresses as a series of incremental curves approximating to a straight line, the slope of which depends on the aggressiveness of the environment.

在未经强化耐蚀处理的结构钢上形成的锈层具有多孔性，并在一定时间后从金属表面脱落，腐蚀周期随之重新开始。因此，锈蚀速率呈一系列近似直线的递增曲线发展，其斜率取决于环境的腐蚀性。

With weathering steel, the rusting process is initiated in the same way, but the specific alloying elements in the steel produce a stable rust layer that adheres to the base metal and is much less porous than the layers on steel without an enhanced resistance. This rust 'patina' develops under conditions of alternate wetting and drying to produce a protective barrier that impedes further access of oxygen, moisture and pollutants.The result is a lower corrosion rate than for ordinary structural steel. The degree of protection afforded depends on the environmental and other conditions prevailing at the site of the structure.

对于耐候钢，锈蚀过程以相同的方式启动，但钢材中的特定合金元素会形成一层稳定的锈层，这层锈层附着在基体金属上，且比未增强耐蚀性的钢材上的锈层致密得多。这种锈层“包浆”在交替潮湿和干燥的条件下形成，产生一层保护屏障，阻碍氧气、水分和污染物的进一步侵入。其结果是腐蚀速率低于普通结构钢。所提供的保护程度取决于结构所在地方的环境和其他条件。

What is an EAD?什么是EAD？

A European Assessment Document, or EAD for short, is a harmonised technical specification developed by EOTA as the basis for European Technical Assessments (ETAs).上海郜盟提示欧洲评估文件（简称EAD）是由欧洲技术认证组织（EOTA）制定的统一技术规范，作为欧洲技术评估（ETA）的基础。

In combination with the ETA, the EAD provides manufacturers with a way to CE marking for construction products that are not or not fully covered by a harmonised European standard (hEN) under the Construction Products Regulation (EU) 305/2011. The CE marking allows the manufacturer to freely market his product in the entire European Economic Area as well as in Switzerland and Turkey.

结合ETA，EAD为制造商提供了一种对未被或未完全被《建筑产品法规》（EU）305/2011所涵盖的协调欧洲标准（hEN）覆盖的建筑产品进行CE标志认证的途径。获得CE标志后，制造商即可在全部欧洲经济区以及瑞士和土耳其自由销售其产品。

Finished floor or ceiling covering as well as possible sound reducing materials are not part of the kit.

完成的地板或天花板覆盖物以及可能的隔音材料不属于套件的一部分。

This EAD is not applicable when

-recycled material is used.

此 EAD 在下列情况下不适用:

-使用了回收材料。

关于产品的包装、运输、储存、维护、更换和修理事宜，制造商有责任采取相应措施，并在其认为必要的情况下向客户提供有关产品运输、储存、维护、更换及修理方面的建议。

It is assumed that the product will be installed according to the manufacturer's product installation instructions (MPl) or (in absence of such instructions) according to the usual practice of the building professionals

假定该产品将按照制造商的产品安装说明（MPl）进行安装，或者在无此类说明的情况下，则按照建筑专业人员的惯常做法进行安装
