Pre-drilled Carbon Steel Plate

Tianjin Shunchen Industrial is a leading steel product like Pre-drilled Carbon Steel Plate manufacturer with 12 years of export experience, specializing in precision-processed structural steel products. Our Tianjin production base is equipped with 5 sets of high-speed CNC drilling machines, automatic deburring lines and a full set of dimensional testing equipment, supported by a national-level material testing laboratory. We focus on R&D and production of precision drilled carbon steel plates, optimized for fast installation and cost reduction in engineering and manufacturing scenarios.

Unlike ordinary blank steel plates that require customers to perform secondary drilling with low precision and high labor cost, our products adopt programmed CNC drilling technology, with one-time forming of all hole positions strictly based on customer drawings. Our quality control engineer Sun Tao, with 10 years of experience in steel fabrication inspection, personally supervises full-process inspection of each batch, ensuring hole position deviation ≤±0.2mm and no burrs or cracks at hole edges. All products comply with GB, ASTM, EN and JIS standards, and can provide complete mill test certificates (MTC EN 10204 3.1) and third-party SGS inspection reports.

Real-world Performance Testing

1. Hole Position Accuracy Verification Test

Test Standard: GB/T 1804-m, ASTM A6

Test Samples: Manual on-site drilled plate, Tianjin Shunchen CNC pre-drilled plate

Key Findings:

Manual drilling: Average hole position deviation ±1.2mm, maximum deviation up to 2.5mm, assembly rework rate 12%

Our CNC drilled plate: Hole position deviation ≤±0.2mm, 6 times higher accuracy, 100% one-time assembly matching rate

2. Hole Edge Quality & Mechanical Performance Test

Test Items: Hole edge crack detection, tensile strength comparison before and after drilling

Test Results:

Hole edge: Fully deburred and chamfered, no micro-cracks, no stress concentration

Mechanical properties: Tensile strength, yield strength and elongation remain consistent with the original base plate, no performance loss caused by drilling process

3. On-site Assembly Efficiency Test

Test Scenario: Simulated steel structure embedded plate installation, 100 pieces of plates with 4 holes each

Test Results:

On-site drilling + installation: 32 working hours in total

Using our pre-drilled plate for direct installation: 8 working hours in total, construction efficiency increased by 75%

Real-world User Scenarios & Verified Cases

Case 1: Jiangsu Steel Structure Workshop Embedded Plate Project

Industry: Steel structure construction

Problem: The project had a large number of embedded plates. On-site manual drilling had low efficiency and large position deviation, causing misalignment of steel column installation and project delay.

Solution: Adopt our Q235B pre-drilled carbon steel plate (16mm thickness), with all holes drilled precisely according to construction drawings, matching the size of steel column anchor bolts, fully processed before delivery.

Result: Installation efficiency increased by 65%, hole position matching rate reached 100%, project duration shortened by 12 days, on-site processing cost reduced by 45%. Cumulative purchase volume reaches 1,200 tons, with 5 years of ongoing cooperation.、

Case 2: Shandong Heavy Machinery Equipment Base Plate Project

Industry: Machinery equipment manufacturing

Problem: Self-drilled base plates for heavy equipment had insufficient precision, leading to equipment assembly misalignment, abnormal vibration and 8% rework rate.

Solution: Adopt our Q355B pre-drilled carbon steel plate (20mm thickness), drilled strictly according to equipment assembly drawings, with deburred and chamfered hole edges, ready for assembly directly.

Result: Assembly rework rate dropped from 8% to 0.5%, production efficiency increased by 40%, and processing cost per unit reduced by 28%. Annual purchase volume reaches 450 tons.

Authentic Customer Reviews

"We have used Tianjin Shunchen's pre-drilled embedded plates for 5 years in steel structure projects. The hole position accuracy is extremely high, which greatly saves our on-site processing time and reduces rework. Their delivery is always on time, which strongly supports our project schedule." —— Zhou Jian, Project Manager, Jiangsu Hongda Steel Structure Engineering Co., Ltd.

"For heavy equipment base processing, hole position accuracy directly determines assembly quality. Their CNC drilled plates have stable precision, which has helped us reduce the rework rate significantly. We don't need to arrange separate drilling processes now, and the production efficiency has improved a lot." —— Wang Qiang, Production Director, Shandong Heavy Machinery Manufacturing Co., Ltd.
