濟(jì)南方管:兩大優(yōu)勢(shì)及多樣的材質(zhì)

發(fā)布時(shí)間:2025-04-08 來源:http://m.gp552.com/

1.方管的橫截面是規(guī)則的四邊形,就像一個(gè)空心的鋼鐵盒子,四個(gè)邊的長(zhǎng)度可以相同(稱為方管)或不同(稱為矩形管),這種結(jié)構(gòu)讓它兼具兩大優(yōu)勢(shì):

The cross-section of a square tube is a regular quadrilateral, like a hollow steel box. The lengths of the four sides can be the same (called a square tube) or different (called a rectangular tube), which gives it two major advantages:

承重能力強(qiáng):相同截面積下,方管的抗彎強(qiáng)度比圓管高 30% 以上,因?yàn)榉叫谓孛娴睦饨欠植寄芨鶆虻胤稚毫?。例如,搭建腳手架時(shí),邊長(zhǎng) 40 毫米、壁厚 3 毫米的方管,單根可承重 500 公斤,適合作為垂直支撐柱,穩(wěn)定可靠。

Strong load-bearing capacity: Under the same cross-sectional area, the bending strength of square pipes is more than 30% higher than that of round pipes, because the angular distribution of square sections can more evenly distribute pressure. For example, when building scaffolding, a square tube with a side length of 40 millimeters and a wall thickness of 3 millimeters can support a single weight of 500 kilograms, making it suitable as a vertical support column and stable and reliable.

連接便捷:方管的直角邊便于焊接、螺栓固定或卡扣連接,無需復(fù)雜的圓弧加工。在家具制作中,方管的四個(gè)平面可以直接與板材貼合,用螺絲固定后形成牢固的框架,比圓管節(jié)省 30% 的連接時(shí)間。

Convenient connection: The right angled edges of the square tube are easy to weld, bolt, or snap connect, without the need for complex arc machining. In furniture production, the four flat surfaces of square tubes can be directly attached to the board and fixed with screws to form a sturdy frame, saving 30% of connection time compared to round tubes.

2.多樣材質(zhì):適配不同場(chǎng)景的 “鋼鐵外衣”

2. Diverse materials: "Steel outerwear" suitable for different scenarios

濟(jì)南方管的材質(zhì)選擇豐富,每種材質(zhì)都像為特定環(huán)境定制的 “防護(hù)鎧甲”:

Jinan square tube has a wide selection of materials, each of which is like a customized "protective armor" for a specific environment:

碳鋼方管

Carbon steel square tube

以 Q235B 碳鋼為原料,表面多做鍍鋅處理(熱鍍鋅或電鍍鋅),鋅層厚度 8-275 克 / 平方米,就像給鋼材穿上 “防銹外套”。這種方管性價(jià)比高,適合室內(nèi)干燥環(huán)境或普通戶外場(chǎng)景,如建筑中的隔墻龍骨、工廠的設(shè)備支架。例如,家庭裝修中常用的邊長(zhǎng) 20×40 毫米、壁厚 1.5 毫米的碳鋼方管,搭配木質(zhì)板材制成書架,既承重又不易生銹。

Using Q235B carbon steel as raw material, the surface is treated with galvanizing (hot-dip galvanizing or electroplating), with a zinc layer thickness of 8-275 grams per square meter, just like putting a "rust proof jacket" on the steel. This type of square tube has a high cost performance ratio and is suitable for indoor dry environments or ordinary outdoor scenes, such as wall studs in buildings and equipment brackets in factories. For example, the commonly used carbon steel square tube with a side length of 20 × 40 millimeters and a wall thickness of 1.5 millimeters in home decoration, combined with wooden boards to make bookshelves, not only bears weight but is also not easy to rust.

不銹鋼方管

Stainless steel square tube

采用 304 或 316 不銹鋼,表面光滑且耐腐蝕,能抵抗?jié)峡諝庵械臐駳夂洼p微酸雨,適合潮濕環(huán)境或?qū)γ烙^要求高的場(chǎng)所。304 不銹鋼方管常見于商場(chǎng)的扶手、酒店的裝飾框架,316 不銹鋼方管則用于化工車間的耐腐蝕管道,即使長(zhǎng)期接觸水汽或腐蝕性液體,也能保持表面光潔,使用壽命可達(dá) 20 年以上。

Made of 304 or 316 stainless steel, the surface is smooth and corrosion-resistant, able to resist moisture and slight acid rain in Jinan air, suitable for humid environments or places with high aesthetic requirements. 304 stainless steel square tube is commonly used in handrails in shopping malls and decorative frames in hotels, while 316 stainless steel square tube is used for corrosion-resistant pipelines in chemical workshops. Even if it comes into long-term contact with water vapor or corrosive liquids, it can maintain a smooth surface and have a service life of over 20 years.

鋁合金方管

Aluminum alloy square tube

重量?jī)H為碳鋼的 1/3,表面經(jīng)陽極氧化處理形成致密氧化膜,輕便耐用且無需額外防銹,適合對(duì)承重要求不高但需要靈活移動(dòng)的場(chǎng)景。濟(jì)南的戶外廣告架、展覽展示架常使用鋁合金方管,邊長(zhǎng) 30×50 毫米、壁厚 1.2 毫米的規(guī)格,既能支撐廣告畫面,又便于運(yùn)輸和安裝。

The weight is only one-third of carbon steel, and the surface has been anodized to form a dense oxide film. It is lightweight, durable, and does not require additional rust prevention, making it suitable for scenarios that do not require high load-bearing requirements but require flexible movement. Outdoor advertising and exhibition display stands in Jinan often use aluminum alloy square tubes with a side length of 30 × 50 millimeters and a wall thickness of 1.2 millimeters, which can support advertising images and facilitate transportation and installation.
