WHAT ARE STAINLESS STEEL LETTERS - RAISED STAINLESS STEEL LETTERS?
Stainless steel is a type of hard steel consisting of two types: rust-resistant and rust-prone.
The rust-resistant type is called Stainless Steel 304, which is more flexible.
The rust-prone type is called Stainless Steel 201 & 430, which contains manganese and less nickel, making it harder and cheaper than Stainless Steel 304. Note: It is very difficult to distinguish Stainless Steel 304 from 201 by the naked eye. Only after some time of use can you tell whether it is 304 or 201.
Stainless Steel Letters use stainless steel sheets with thickness from 0.2mm to 10mm, cut into letters (flat letters according to the thickness of the stainless steel).
Raised Stainless Steel Letters use stainless steel sheets with thickness from 0.5mm to 2mm, cut into letters with bent legs and raised sides attached to the letter face. The height of the letters can be customized.
HOW MANY TYPES OF STAINLESS STEEL ARE THERE BEFORE MAKING THE FINISHED PRODUCT?
There are 4 types of stainless steel before making the finished product:
Stainless steel sheet 304 or 201 with size: 1.22m x 2.44m
Stainless steel coil 304 or 201 with size: 1.22m x over 100 meters long
Note: In terms of price, stainless steel sheets are more expensive than coils, but the letters will be more beautiful and flatter without waves.
HOW MANY COLORS DO STAINLESS STEEL LETTERS HAVE WHEN FINISHED?
Before 2010, stainless steel had 3 basic colors: shiny gold, shiny white, and matte brushed white.
From 2011, there are over 7 common colors from manufacturers: mirror white, brushed gold, classic antique glossy red, classic antique brushed red, glossy black, matte black, dark blue...
From 2015, we have applied plating technology such as chrome plating and nickel plating on stainless steel to produce colors according to customer preferences. However, the cost is very high due to the complex pre-plating process.
We can also use heat-cured paint technology on stainless steel letters to get the desired color.
WHY USE OR CHOOSE STAINLESS STEEL LETTERS?
If you choose simplicity, elegance, class, durability, and sophistication with sharp edges, stainless steel letters are considered the most suitable. The beauty of mirror gold stainless steel is glossy, mirror white stainless steel at 800K is dazzling like a mirror, matte brushed white stainless steel is gentle, brushed red stainless steel is classically sophisticated, black stainless steel is mild and gentle, and brushed gold stainless steel is luxurious...
Customers can also choose unique colors not readily available on the market by chrome plating or nickel plating to create a distinctive product, but the cost will be double.
The outstanding advantage of stainless steel letters is beauty and durability over time, especially they do not rust when exposed to rain and sun, do not peel off, and do not deform if you choose a professional manufacturer.
CAN STAINLESS STEEL LETTERS BE FITTED WITH LIGHTS?
Stainless steel letters can be fitted with lights, including the following 5 options:
Option 1: Backlit letters + stainless steel face, with lights installed inside the back of the letter, light reflecting onto the wall behind the letter.
Option 2: Partially front-lit letters + stainless steel side edges, stainless steel contour face creating lines: the letter face is inlaid with mica and the back for LED installation is made of formex, aluminum, stainless steel, mica...
Option 3: Fully front-lit letters + stainless steel side edges and back, letter face made of mica. Inside fitted with LED lights fully illuminating the letter face...
Option 4: Side-lit raised block letters + stainless steel face and side legs, back lined with a solid mica layer. LED lights installed inside to illuminate the letter legs.
Option 5: Solid 3D letters lit on face and legs + letter sides made of stainless steel or spray-painted in color. Letter face and back made of solid mica cut by CNC to create 3D beveled edge effect. LED lights installed inside to illuminate both sides with two different colors.
WHO ARE THE CUSTOMERS OR BRANDS THAT USUALLY INSTALL STAINLESS STEEL LETTERS WITH OR WITHOUT LIGHTS FOR NIGHT DISPLAY?
Group 1: Install letters with lighting + Hotels, restaurants, high-end apartments, shopping malls, banks, fashion shops, cosmetics shops, beauty clinics, showrooms...
Group 2: Install letters without lighting + Government agencies, military camps, factories in industrial zones, schools, hospitals, cultural houses, apartment complexes...
SINCE WHEN HAVE STAINLESS STEEL LETTERS BEEN WIDELY USED IN VIETNAM?
From 1995 to 2008, very few units accepted stainless steel letter fabrication. These units were all in Ho Chi Minh City and Hanoi. All processes were done by hand without machine support, requiring many workers and resulting in very high costs. Therefore, only large units such as restaurants, hotels, industrial zones, and government agencies needing durability, beauty, and sturdiness chose to install them.
From 2009 to 2020, many advertising units accessed technology and purchased advanced machinery, speeding up production. Thus, costs decreased and beautiful designs were created, increasing popularity among users.
PRODUCTION TIME FOR A SET OF LETTERS MADE BY PROFESSIONAL MACHINES VS. HANDMADE WITHOUT MACHINES?
Production time for a set of stainless steel letters, for example the word "ADVERTING" with 9 letters, size (height x width x thickness): 20 x 140 x 5 cm.
A manufacturer with professional machinery: completes one set in 3 hours.
A manufacturer working manually without machinery: takes 12 hours to complete one set. (Here we only talk about production time, not comparing quality).
HOW HAS THE PRODUCTION PROCESS OF STAINLESS STEEL LETTERS CHANGED FROM 1995 TO 2020?
Phase 1: From 1995 to 2002, letters were printed or drawn on paper and stuck onto stainless steel. A handheld scroll saw (type 2 or 3 used in jewelry) was used to cut the letter face. Then pliers bent the sharp legs to form the letter sides. A torch was used to heat the welding tip to melt solder and bond the sides to the letter face. After completion, the letters were soaked in water to wash off acid, then cooled, cleaned, and packaged.
Phase 2: From 2003 to 2012, decals were cut and stuck onto stainless steel face. A handheld power saw was used to cut the letter face. Then pliers bent the sharp legs to form the letter sides. A torch was used to heat the welding tip to melt solder and bond the sides to the letter face. After completion, the letters were soaked in water to wash off acid, then cooled, cleaned, and packaged.
Phase 3: From 2013 to 2020, stainless steel letters were cut by computer-controlled plasma or laser machines. Letter sides were bent by computer-controlled bending machines. The sides and letter face were bonded by laser welding machines. Letters were inspected and packaged for delivery. Access to technology and investment in machinery greatly increased production efficiency, reduced labor costs, and intensified competition.
WHO WAS THE BEST STAINLESS STEEL LETTER CRAFTSMAN IN VIETNAM BEFORE 2005 WHEN THERE WAS NO MACHINE SUPPORT?
Currently, stainless steel letter production is no longer very difficult, but those who have been in the trade for a long time and appreciate beauty, gloss, and durability will know Uncle Nam Cut. Why is he called Uncle Nam Cut? Because he has only one leg and usually moves by cyclo. His home and workshop are in Ho Thi Ky area, Ward 1, District 10, Ho Chi Minh City. When I was young, I had many opportunities to meet and work with him. He managed a team of craftsmen specializing in stainless steel letters. It can be said that the letters produced by his unit at that time were the most beautiful in Vietnam.
* To confirm a beautiful stainless steel letter set at that time, the following factors were considered:
Letter lines had to be sharp, cuts straight, letter faces without waves. The raised side edges had to be square, welds smooth and even, and importantly, no one noticed that the mounting brackets for hanging letters never showed screws (because all were hidden inside). This made installation harder but achieved high aesthetics.
Specifically, those who love the trade like me always seek to learn the newest things and never ask why they could make such beautiful, sharp products at a time when everything was done by hand with very hard stainless steel sheets.
Uncle's achievements included signing many contracts with big brands at that time. When he grew old, he passed away suddenly. His legacy was a team of skilled craftsmen, major clients, and a son who inherited the business.
HOW MUCH DOES IT COST TO INVEST IN A PROFESSIONAL STAINLESS STEEL LETTER MAKING MACHINE SET?
To invest in a complete professional stainless steel letter-making machine set, the following machines are needed:
1 large-format Plasma cutting machine or Laser cutting machine / price: 980 million VND.
1 letter leg bending machine, able to bend side legs up to 20 cm high / price: 280 million VND.
1 laser welding machine to bond sides and letter face / price: 180 million VND.
Total for 3 items: 1,440,000,000 VND.
* With the above cost, we import machines from China, but they still work well for many years.
