一般情况下我们使用的护栏分为两种：锻钢护栏和铸铁护栏。那么这两种护栏的区别是什么呢？
锻钢护栏的优点：是加工安装方便、缺点是花样不多价格过高。铸铁护栏的表面比较粗犷，含碳量高，容易断裂。
铸铁护栏的优点：是图样加工灵活有图能加工、缺点是加工费有点高。表面比较细腻，含碳量低，有韧性扭曲度强。锻钢护栏一般都才用刷漆，价格较便宜一般100-200每米。
铸铁护栏表面采用镀锌+喷塑或喷漆，价格一般在200以上（镀锌可分：热镀锌和冷镀锌，采用热镀锌的室外铁艺围栏*少质保可以8年不生锈，采用冷镀锌的室外铁艺围栏*少质保可以5不生锈，当然热镀锌价格比冷镀锌的贵，喷塑是铁艺表面处理里*好的工艺）
锻钢就是2次烧制出来的熟钢，比较结实，普通的钢不是太结实，锻钢价钱高于普通钢。
In general, we use the barrier is divided into two kinds: forged steel guardrail and cast iron fence. So what is the difference between these two kinds of guardrail?
: the advantages of forged steel guardrail is processing and easy installation, the disadvantage is that figure is not much price is too high. The surface of cast iron guardrail is straightforward, carbon content is high, easy to fracture.
: the advantages of cast iron guardrail is flexible pattern processing can figure processing, the disadvantages are processing fee is a little high. Surface is exquisite, low carbon content, has a strong toughness distortion. Forged steel guardrail is general to brush paint, prices cheaper generally 100-200 per meter.
Cast iron fence use galvanized + plastic and spray paint surface, the price is in commonly 200 above (galvanized can be divided into: hot dip galvanized and cold galvanized, hot galvanizing outdoor, wrought iron fence, at least on the quality assurance can be eight years does not rust, cold galvanized outdoor, wrought iron fence at least quality assurance May 5 does not rust, hot dip galvanized, of course, price is expensive, cold galvanized coating is one of the best in the wrought iron surface treatment process)
Forged steel is fired twice cooked steel, more strong, not was too strong, ordinary steel forging steel price is higher than ordinary steel.
